a boy runs along a straight road for 10 minutes at a speed of 3m/s. The boy tires and walks for 5 minutes at 1 m/s. Calculate the total distance traveled by the boy

Respuesta :

Distance traveled in 10 minutes(600sec)
=speed×time
=3m/s×600s
=1800m

Distance traveled in 5 min (300sec)

=1×300
=300m

So total distance=1800+300=2100m
