Question

a certain journey from A to B is covered by 80 km/hr and returning at 40 km/hr total journey in 6hours find the distance

Answer 1

we know d=st

here we have to consider average speed

avg speed=2xy/(x+y)

=>avg speed=2*80*40/(80+40)

here avg speed is approximately =53.33kms

we know d=st

=>d=53.33*6

=>d=320kms
