From city A to city B a bus left 60 km / h after 2 hours the car left after what time

From city A to city B a bus left 60 km / h after 2 hours the car left after what time the car will catch up with the bus if 30 km more in an hour.

The desired unspecified number of hours, after which the car will catch up with the bus, is defined through the conditional variable “Y”.
By the second action, using the formula for the speed and taking into account the conditions of this problem, we compose this equation: Y = (60 x 2) / 30.
When we solve this equation, we get the following Y = 120/30 = 4 hours.
Answer: in 4 hours the car will catch up with the bus.
