If a marathon runner averages 6.3 mi/h, how long does it take him or her to run a 26.22-mi marathon?
If a marathon runner averages 6.3 mi/h, how long does it take him or her to run a 26.22-mi marathon?
Given that the average speed of the marathon runner is 6.3mi/h, and the total distance covered in the marathon is 26.22mi. Average speed is defined as the total distance traveled by the object divided by the elapsed time to cover that distance. Thus the expression for the time of run can be obtained from the definition of average speed as shown below.
Substitute 6.3 mi/h for vav, and 26.22mi for d in the obtained expression for t to...
