Question

How fast is a man running (in mph's) if he runs the 100 meters in 9.69 seconds?

Answer 1

It's approximately 23.08 mph.

You need to find out how many meters per second by dividing 100 / 9.69.

Then you multiply that by 3600 (amount of seconds in an hour) to find out how many meters he would run in an hour, and then convert that to miles.

Answer 2

about 22.6 mph

Answer 3

if my math is correct, 22.4mph
