In 2008, the world record for swimming the 50 meter freestyle event was 21.34 seconds. Supposing the athlete swam at a constant rate, what was his speed? Round your answer to the nearest hundredth.

2.34m/s

Step-by-step explanation:

says that he swim a distance of 50 meters in 21.34 seconds

21.34s = 50m

if we want to know how much it travels in 1 second we would have to divide by the amount of seconds both parts

21.34s = 50m

21.34s/21.34 = 50m/21.34

1s = 2.343m

if in 1 second it makes a distance of 2.343 meters this means that its speed is 2.343 meters over seconds (m/s)

we have to round to the nearest hundredth so that instead of 2.343m/s it would be 2.34m/s
