Two places A and B are 60 km apart from each other on a highway. A car starts from A and another car from B at the same time. If they move in the same direction, they meet each other in 6 hours. If they move in the opposite direction towards each other, they meet in 1 hour 30 minutes. Find the speeds of the cars (in km/h).

Correct option is C

Distance = Speed × Time
Let the speed of car A and B be x and y respectively.
When they move in same direction.
(x – y) = 60/6
(x-y)= 10.....(1)
When they move in opposite direction.
(x + y) = 60/1.5
x+ y = 40.....(2)
On solving 1 and 2
x = 25 km/hr and y = 15 km/hr
