Abdul, while driving to school, computes the average speed for his trip to be 20 km h^(-1). On his return trip along the same route, there is less traffic and the average speed is 30 km h^(-1). What is the average speed for Abdul's trip?

A car travels at a speed of 80 km/h during the first half of its running time and at 40 km/h during the other half. Find the average speed of the car. (60 km/h) ( AS_(7))

A man walks on a straight road form his home to a market 2.5 km away with speed of 5 (km)/(hr) . Finding the market closed, he instantly turns and walks back home with a speed of 7.5 (km)/(hr) . The average speed of the man over the intervel of time 0 to 40 min is equal to

The speed of a motorcycle is 40 km h^(-1) for first 10 minute and 50 km h^(-1) for the next 10 minute, then the average speed of this motorcycle during the 20 minute would be ......... km h^(-1).

An express train takes 1 hour less than a passenger train to travel 132 km between Mysore and Bangaluru (without taking into consideration the time they stop at intermediate stations). If the average speed of the express train is 11km/h more than that of the passenger train, find the average speed of the two trains.

A particle moving in a straight line covers half the distance with speed of 3 m//s . The half of the distance is covered in two equal intervals with speed of 4.5 m//s and 7.5 m//s respectively. The average speed of the particle during this motion is :
