A bus and a car move toward each other. The speed of the bus is 50 km/hr, and the speed of the car is 70 km/hr. How much closer do the vehicles get every hour?
When the bus and car move towards each other, their speeds are added together. Therefore, the vehicles are getting closer at a rate of 50 km/hr + 70 km/hr = <<50+70=120>>120 km/hr.
