Time & Distance

Question
23 out of 35
 

Aditya covered a certain distance at some speed. Had he moved 3 km/h faster he would have taken 40 minute less. If he had moved 2 km/h slower he would have been taken 40 minutes more. The distance is-



A 40
B 35
C 49
D 45
E None of these

Ans. A

Let distance = x km and usual rate = y km/h

Then,

On dividing (i) by (ii) we get x = 40

Let the distance travelled on foot by x km. Then, distance travelled on bicycle = (122 – x)

9x + 4(122 – x) = 18 × 36

5x = 648 – 488

5x = 160

x = 32 km
