Answer 2

A person walks 60 meters in 1 minute. Then walks 30 meters in 2 minutes. What is their average speed over the 3 minute walk?

Explanation:

Speed of a body is the amount of distance it covers per unit time.

For the given problem, let us determine the speed in meters per minute

total distance traveled = 60+30 = 90 m

total time taken= 1+2 = 3 minutes

average speed per minute= total distance traveled/total time taken

=90/3 = 30 m/minute
