62.1 miles are obtained by dividing 621 miles by 100. That implies a 100-kilometer race will be 62.1 miles long. That is a long distance!

The average speed of a car is 60 miles per hour. If you start together at noon from a point where there is no traffic allowed, then one person will arrive after about 5 hours and the other after about 4 hours. This means that the distance between them will have reduced by **20 percent** in 4 hours, or at a rate of **10 kilometers** per hour!

The total distance covered in a year by the sun at the Earth's surface is about 40 million miles, or half the distance to the moon. That means that if the sun were instead as close as the moon, we would only get **12 hours** of daylight **at twice the current latitude**.

The sun is very powerful: it can blow things away, melt metals, even turn water into steam. The earth's atmosphere protects us from most of its energy but not all of it. If it weren't for the clouds, sunlight still contains enough energy to burn paper but not enough to warm up the planet significantly.

The cloud cover varies a lot from place to place and over time. In general, more cloud coverage means **less direct sunlight** and thus cooler temperatures.

How far is it? The 800-meter race is sometimes referred to as **the half-mile race**. However, we know that this is just slightly inaccurate because 800 meters equals **0.49709695379 miles**, not nearly 0.5 miles. Similarly, the 1600-meter run is sometimes referred to as the mile run. But it's about 1.609 kilometers or 0.9992 miles.

Why don't we call it the quarter-mile race? Because 400 meters equals **0.2000059881 miles**, which is almost exactly quarter of a mile.

So the half-mile race is really only 500 meters, or 0.25 miles. This makes sense because you can run the half-mile in less than 11 seconds, but it takes more than 5 minutes to walk the half-mile!

However, the term "half-mile" has become popular among runners because it's easy to remember. If you say the word "half" before something, people usually understand what you're talking about. For example, if I say "I ran the block last night" most people will assume that I mean I ran half of a block, rather than a whole block.

In fact, according to some sources, the term "half-mile" was first used by Dr. William Brooks in his book Sports Medicine: A Handbook for Athletes, Trainers, and Coaches in 1942.

38.53 miles = 62 kilometers. Calculate the value in kilometers by multiplying it by the conversion factor '0.6213711922371'. So, 62 kilometers = 62 multiplied by 0.6213711922371 equals 38.5250139187 miles.

The conversion factor from kilometers to miles is 0.6213711922371. It was discovered by **Isaac Newton** and was first published in A New System of World Geography, written by Newton with an introduction by William Harvey. It is also called "Newton's Meter".

Newton's method is a method of solving equations that includes dividing each side of the equation by the opposite side to obtain a number which is then multiplied by itself to get a better estimate of the answer.

In **our case**, we have divided **both sides** of the equation km = mi*k(-1)^n where n is the number of times that we multiply by itself which gives us **km/mi * k(-1)^(3*n+1**). Now since km/mi is known, we can solve for k which gives us (-1)^(3*n+1)/km or -1/(3*n+1). Multiply this number by mi and you get the result in miles.

62.1 miles.

The Chicago Marathon starts and finishes at the Chicago Lincoln Park Zoo, which is also the course record for most consecutive miles covered in one race. In 2007, all-time great Dennis Kimetto ran from start to finish of the race in 2:14:26, covering 100 kilometers (62 miles) without stopping. The previous record was held by **Abdi Abdirahman** with a time of 2:20:44, which was set in 2005. Kimetto's time has since been broken but he remains the champion marathoner of Japan.

The Tokyo Marathon begins and ends at **the Tokyo International Forum**, which is also the longest marathon in Japan at 26.08 miles. It was first held in 1983 and became a World Marathon Majors event in 2014. The top three men's and top three women's times qualify athletes for the Boston Marathon. Women have competed since 1985, when Japanese women were first allowed to enter **domestic races**.

The Hanover Marathon is an annual road running event over two loops on either side of the River Lea in Hertfordshire, England.

6.2 miles Pause, repeat after me: Here's a breakdown of the 10,000. The letter "K" stands for kilometer, which is equivalent to **0.62 miles** or 1093.6 yards (http://www.metric-conversions.org). A 10K is therefore 10 kilometers (10,000 meters), or 6.2 miles. It's twice the length of a 5K race.

55920 miles.

74,5645428 miles = 120 kilometers.

As a result, 100 air miles equal 115.08 statute miles, or 185.2 kilometers.

The conversion factor for **air miles** to **ground miles** is 0.624. So, all you need to do is divide the number of air miles by 0.624 to find the number of ground miles.

Thus, 100 air miles = 185.2 kilometers.
