Question

The Boston Marathon covers 26.2 miles in a course that runs up and down hills through many parts of the city. The current record time is 2.0334 hours. What was the average speed required to create this pace in meters/second?

a) 2.65 m/s
b) 3.04 m/s
c) 4.13 m/s
d) 5.19 m/s

Answer 1

The average speed required to create the record time in the Boston Marathon is 5.76 m/s.

Step-by-step explanation:

To find the average speed in meters per second, we need to convert the distance traveled from miles to meters and the time taken from hours to seconds. The Boston Marathon covers 26.2 miles, which is equal to 42,188 meters, and the record time is 2.0334 hours, which is equal to 7,321.44 seconds. To calculate the average speed, we divide the distance by the time:

Average speed = Distance / Time = 42,188 meters / 7,321.44 seconds = 5.76 meters/second

Therefore, the average speed required to create this pace is 5.76 m/s (option d).
