Answer 1

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

Answer 2

1. we know that s=d/t
2. speed of car is 72/2=36

4. hence ratio of their speeds will be 36:40 which is 9:10
