Question

Ramu and salim travelled to thiruvananthapuram from the same place , each in his own car . Ramu did the onward journey at an average speed of 120 km/h and the return at 50km/h . Salim did both trip at 60 km/h . Who made the total journey in less time ?

Answer 1

Answer:

ramu made the total journey in less time

Step-by-step explanation:

let say distance = d for one side

time taken by Ramu = d/120 + d/50

= (5d + 12d)/600

= 17d/600

time taken by salim = d/60 + d/60 =2d/60

= 20d/600

17d/600 < 20d/600

hence ramu made the total journey in less time.
