Question

Rita takes 20 min to cover distance 3.2 km on a bicycle her velocity in units of m/s

Answer 1

velocity is0.16 m/s
by dividing distance from time.

Answer 2

Answer:

first we change km into m and minute into second

1min=60sec

20min=60×20=1200 sec

1km=1000m

3.2km=3.2×1000 =3200m

velocity =D/t

3200/1200 =2.6 m/sec
