Question

A bus covers certain distance with a speed of 40 km/hr and the same distance with a speed of 20m/s.Calculate the average speed.​

Answer 1

AnsweR :

A bus travels a distance with speed of 40 km/h then travels same distance with speed of 20 m/s.

Convert km/h to m/s by multiplying it by 5/18

⇒Speed = 40 * 5/18

⇒Speed = 200/18

⇒Speed = 11.12 m/s

___________________

For average speed

⇒Avg Speed = (11.12 + 20)/2

⇒Avg Speed = 31.12/2

⇒Avg Speed = 15.56

➭ Average speed is 15.56 m/s.
