Hey MATE!
1) Distance travelled by car = 72 km
Time taken. = 2hr
Speed of car = 72/2 ==> 36 km/hr
2) Distance by train = 120 km
Time taken = 3 hr
Spees of train = 120/3 = 40 km/hr
Ratio of speed of car to train is :
36 : 40 ==> 9:10 Answer
Hope it helps

- we know that s=d/t
- speed of car is 72/2=36
- simalarly speed of train is 120/3=40
- hence ratio of their speeds will be 36:40 which is 9:10
