A bus travel one third of the distance with a speed of `12 km h^(-1)` and the remaining distance with a speed of `20 km h^(-1)` . The average speed of the bus is __________ `km h^(-1)`

A body moves with a unifrom speed of 10 km h^(-1) for 2h. The average speed of the body is ______ km h^(-1)

A car is moving on a straight road covers one third of the distance with a speed of 20 km/h and the rest with a speed of 60 km/h. The average speed of the car is

A car is moving on a straight road covers one third of the distance with a speed of 20 km/h and the rest with a speed of 60 km/h. The average speed of the car is

A car is moving on a straight road covers one third of the distance with a speed of 30 km/h and the rest with a speed of 50 km/h. The average speed of the car is

A car covers (1)/(3) part of total distance with a speed of 20 km h^(-1) and second 1 /3 and the last part with a speed of 60 km h^(1) The average speed of the car is:

An object had covered 120 km distance, half of this distance was covered at 20 km h^(-1) speed and the remaining distance at 30 km h^(-1). Then its average speed is said to be 25 km h^(-1) ,
