A train can travel 50% faster than a car. Both start from point A at the same time and reach point B 75 kms away from A at the same time. On the way, however, the train lost about 12.5 minutes while stopping at the stations. The speed of the car is:
Answer: Option
Explanation:
Let speed of the car be x kmph.
| Then, speed of the train = | 150 | x | = |  |
3 | x |  kmph. |
| 100 | 2 |
 |
75 | - | 75 | = | 125 |
| x | (3/2)x | 10 x 60 |
 |
75 | - | 50 | = | 5 |
| x | x | 24 |
| x = |
|
25 x24 | |
= 120 kmph. |
| 5 |

Hey look it say train travels 50% faster then car. Suppose car travels at x speed than train travels at 50x. So its 150/100 thats as a % age.

When we take 50x/100
we get x=[-75* 24]/5 = - 360kmph
its not in the option
we get x=[-75* 24]/5 = - 360kmph
its not in the option

I think there should be 50x/100 & not 150x/100 is it?

Let car speed be xkmph
then train speed is 50% more than car speed
ie 50/100*x
then train speed is 50% more than car speed
ie 50/100*x
