The answer would be 2.4 meters per second. To find this, you would divide the 50 meters by 21 seconds. It equals 2.380952, and rounds to 2.4m/s.
Answer:
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 = [tex]\frac{50}{21}[/tex]
= 2.380952 rounded to 2.4 meter/sec
The speed of the swimmer is 2.4 meter per second.
