Question

The speeds of three motor bikes are in the ratio 6 : 5 : 4. The ratio between the time taken by them to
travel the same distance is:
(A) 10 : 12 : 15 (B) 12 : 10 : 8
(C) 15 : 12: 10 (D) 10 : 15 : 12

Answer 1

Answer:

10 : 12 : 15

Step-by-step explanation:

DISTANCE = SPEED × TIME.

Let the distance be x!

x = 6 × 10 = 5 × 12 = 4 × 15 ( since all bikes cover same distance )

Therefore the ratio of time of three motor bikes is

10 : 12 : 15
