Answer:

100cm/s

Explanation:

Given the speed of the following students;

Bernard 150 cm/s

Chloe 50 cm/s

Dev 75 cm/s

Eduardo 125cm/s

Their average speed of a student will be the mean of their individual speed as shown:

Average speed = 400/4

Average speed = 100

Hence the average speed of a student is 100cm/s
