Answer:
the speed in the race is 8 meters per second
Step-by-step explanation:
The computation of the speed in the race is shown below:
We know that
Distance = speed × time
where
Distance is 400 meters
And, the time is 50 seconds
So, the speed is
400 = speed × 50 seconds
the speed is 8 meters per second
Hence, the speed in the race is 8 meters per second
