a car travels from stop a to stop b at speed of 30 km per hour and returns back at speed of 50 kmper hour. find the total distance

Question

Arun · Answer

Average speed =total distance /time
let the distance travelled from A to B= x km
then,
total distance travelled = 2x km
time while going from A to B = D/S
=x/30 hours
time while returning = x/50 hours
total time = x/30 + x/50
=5x+ 3x
150
=8x/150
=4x/75 hours
average speed = 2x * 75
4x
37.5 km/hr
