A bus moves with a speed of 40 km/h and covers a distance of 20 km. What is the total time taken by the bus during the whole journey?
1/4 hour
2/3 hour
1 hour
1/2 hour
Time taken = distance covered / speed = 20/40 = 0.5 h.
If the speed of a body is 5m s−1, then the time it would take to cover a distance of 6 km is:
A body moves due East with velocity 20 km/hour and then due North with velocity 15 km/hour. The resultant velocity
A bus travels the first one-fourth of a certain distance with a speed of 20 km/hr, the next one-fourth distance with a speed of 40 km/hr, and the last one-half distance with a speed of 120 km/hr. What is the average speed of the bus for the whole journey?
A wagon weighing 1000 kg is moving with a velocity 50 km/h on smooth horizontal rails. A mass of 250 kg is dropped into it. The velocity with which it moves now is
A truck moves with a speed of 30 km/h for 2 h 30 min. What is the total distance covered by the truck during the whole journey?
