Question

The ratio of the speed of the two trains is 2: 5. If the distances they travel are in the ratio 5:9,find the
ratio of times taken by them.
(a) 2:9
(b) 18:25
(c) 25:18
(d) 10:45

Answer 1

Answer:

Speed×Time=Distance

When Distance is same, speed is inversely

Proportional to time.

So if speed ratio 5:4,time ratio=4:5

5×4=4×5=20 more

Answer 2

Answer:

option (c)25:18

Step-by-step explanation:

Let the speed of

train A=2x

train B=5x

and distance traveled by

train A=5s

train B=9s

Now, time taken by

train A=distance/speed

=5s/2x

train B=9s/5x

so, the ratio of time taken by train A to train B is

=(5s/2x)/(9s/5x)

=25:18
