Question

A car travels a distance 200 on a straight road in two minute and then returns to the starting point in the next four minutes its average speed is

Answer 1

Let the distance taken by a car =200km on straight road

Speed =d/t

=200/2

=100

Distance from return to a starting point in 4 min

Speed=d/t

=200/4

=50

Total distance=150km

Total time taken=6 minute

Average speed = total distance travelled / total time taken

=150km/6min

=25km/min

Thanks i hope it help you
