Question

an object moves through 10 m in 2 minutes and next 10 metre in 3 minutes calculate its average speed.

Answer 1

average speed=total distance/total time taken
=10+10/2+3 =20/5 = 4

Answer 2

Hi..

distance 1 = 10 m
distance 2 = 10 m
time 1 = 2 min = 2×60 = 120 s
time 2 = 3 min = 3×60 = 180 s

avg speed
= (10+10)/(120+180)
= 20/300
= 1/15 m/s

Hope this helps u!!
