Aswimmer swam the 50-meter freestyle in a time of 21 seconds. what was his speed to the nearest tenth of a meter per second?
a. o.4
b. 2.4
c. 23.8
d. 29.0

Speed of swimmer is 2.4 m/s (Approx.)

Given that;

Total distance cover = 50 meter

Time taken to cover distance = 21 second

Find:

Speed of swimmer

Computation:

Speed =  Distance / Time

Speed of swimmer = Total distance cover / Time taken to cover distance

Speed of swimmer = 50 / 21

Speed of swimmer = 2.38 m/s

Speed of swimmer = 2.4 m/s (Approx.)
