Question

An object moves with a uniform speed of 15m/s for 5s and then with a uniform speed of 20m/s for 10s. Find its average speed.

Answer 1

Answer:

Average Speed = Total distance/Total time taken

Step-by-step explanation:

Distance - 15 m/s and 20m/s

Time - 5s and 10s

So total distance = 15+20 = 35m/s

Total time = 5+10 = 15s

Total distance/Total time taken

35m/s divided by 15s

Ans = 7/3ms^-1.
