Question

1. The speeds of three cars are in the ratio 2 : 3:4. The
ratio between the times taken by these cars to travel
the same distance is
(a) 2:3:4
(b) 4: 3:2
(c) 4:3:6
(d) 6:4:3
(e) 3: 4:6​

Answer 1

Answer:

(d) 6:4:3

Step-by-step explanation:

If the distance = x, time taken to cover the distance will by inversely proportional to its speed.

= (x/2) : (x/3) : (x/4) = (6x/12) : (4x/12) : (3x/12) = 6 : 4 : 3
