Question

a object travel 16 m in 4 s and another 16 m in 2s. what is the average speed of object ?

Answer 1

average speed =  total distance / total time taken

total distance = 16+16=32m

total time taken = 4+2=6s

average speed = 32/6 = 5.33m/s{approx}

Answer 2

Avg-speed=16+16/4+2=32/6=5.11m/s
