Rajesh covers the distance by car driving at 60 kmph and returns back to the starting point riding on a scooter at 45 kmph. What is his average speed?

If a person travels a certain distance at a speed of 10 km/h, and returns through the same route at a speed of 20 km/h, then what will be the average speed during the whole journey?

A bus can travel a distance of 1330 Km in 19 hours. Speed of a bike is 50% less than the speed of the bus and speed of a cycle is 15 Km/h less than the speed of the bike. Find the respective ratio of the time taken by cycle and bike to cover a distance of 280 km.

How many kilometers will a cyclist cover in 2 hours 20 minutes with a speed of 5 meters per second?

A takes 2 hours more than B to cover a distance of 40 km. If A doubles his speed, he takes $$1{1\over 2} $$ hours more than B to cover 80 km. To cover a distance of 90 km, how much time will B take travelling at his same speed?

A and B start moving towards each other from places X and Y, respectively, at the same time on the same day. The speed of A is 20% more than that of B. After meeting on the way, A and B take p hours and 72 hours, respectively, to reach Y and X, respectively. What is the value of p?
