Calculating the Difference in Distance Between a Marathon and a Half Marathon

To calculate the difference in distance between a marathon and a half marathon, we can use the given information that a marathon distance is 42 kilometers and a half marathon distance is twice as short as a marathon.

Step 1: Determine the Distance of a Half Marathon The distance of a half marathon can be calculated by dividing the distance of a marathon by 2. So, the distance of a half marathon = 42 km / 2 = 21 km.

Step 2: Calculate the Difference in Distance To find out how much shorter the half marathon distance is compared to the marathon distance, we subtract the distance of the half marathon from the distance of the marathon. So, the difference in distance = 42 km - 21 km = 21 km.

Therefore, the half marathon distance is 21 kilometers shorter than the marathon distance.
