Question

an object moves 18 m in the first 3 s 22 m in the next 3 so and 14 m in the last 3 s. what is its average speed?

Answer 1

average speed= total distance/total time taken
18+22+14/9=6 m/s
average speed = 6 m/s

Answer 2

Average speed = Total distance / Total time
= (18 + 22 + 14)m / (3 + 3 + 3)s
= 54 m / 9 s
= 6 m/s

Average speed is 6 m/s
