Question

suppose a bus travels at the speed of 80km/h . it covers next 360 km at a speed of 90km/h. what is it's average speed.​

Answer 1

Firstly it covers 80km in hour

The it covers 360 km with 90km/h

therefore it takes 360/90 = 4 hours to complete the distance 360km

Average speed = Total distance/total time consumed

= A.S = (80+360)/(1+4)

Average Speed = 440/5

Average speed = 88 km/h
