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 = |

How come 125 and why divided by 60?

T = D/S
T = 75/X-75/1.5X = 12.5/60.
T = 75/X-75/1.5X = 12.5/60.
