Question

a person walks 15.0 m in 5.00 s, and then walks 12.0 m in 10.00 s. What is the average
speed of the person?

Answer 1

start by dividing 10 secs into 2 groups (it will be easier if the timing is equal) add up 15, 6 and 6, and then divide by 3.

the average speed of the person is 9 meters per 5 seconds
