Ответ:
2.4 meter per second
Step-by-step explanation:
A swimmer swam the 50-meter freestyle in a time of 21 seconds.
Since a swimmer swam in 21 seconds = 50 meters
To calculate his speed in 1 second we will divide the total distance by the total time.
Therefore, he swam in 1 second =
= 2.380952 rounded to 2.4 meter/sec
The speed of the swimmer is 2.4 meter per second.
