A student runs 100 meters in 11 seconds. What is the speed of the student?

Use the following formulas: speed = distance/time; 1 mile = 1609 meters

A.) 9.1 miles per hour

B.) 16 miles per hour

C.) 20.3 miles per hour

D.) 24 miles per hour

Speed has a unit of meters per second in the SI unit system. Speed is the amount of displacement traveled or moved by a moving object or entity per unit time. In this case, we are not limited to only dividing the given data but also converting meters to miles and seconds to hours. The answer to the problem is C. 20.3 miles per hour

Speed = distance / time

speed = 100 / 11

speed = 9.09m/s

to get rid of meters and get miles you want to multiply by 1 mile then divide by 1609 meters. to get hours, you times the amount of seconds in an hour (3600) and divide by 1 hour

9.09m/s * 1mile / 1609m * 3600s / 1 hour = 20.3 miles / hour
