Question

A swimmer swam the 50-meter freestyle in a time of 21 seconds. What was his speed to the nearest tenth of a meter per second?

Answer 1

I believe that the correct answer would be B:2.4

You would want to do 50/21 which would equal 2.38 which you would round to the nearest tenth which is 2.4.

Answer 2

50 / 21 = 2.38 rounds to 2.4 meters per second
