Two cars A and B start simultaneously from a certain place at the speed of 30 km/hr and 45 km/hr respectively. The car B reaches the destination 2 hours earlier than A . What is the distance between the starting point and destination?

If a body covers a distance at the rate of x km/hr and another equal distance at the rate of y km/hr, then the average speed in km/hr is

A sailor sails a distance 48 km along the flow of a river in 8 hours. If it takes 12 hours to return the same distance, then the speed of the flow of the river is

A person travels a certain distance at 3 km/hr and reaches 15 minutes late. If he travels at 4 km/h, he reaches 15 minutes earlier. The distance he has to travel is

Two car riders moving in opposite directions start at the same time from opposite ends of a 150 km long road. Each rider moves at a speed of 50 km per hour. At the moment they start, a fly leaves one of the riders and flies to land on the other. If the fly travels at 80 km/hr, select the option that indicates distance in units the fly needs to travel.
