Question

Z bus covers half the distance at a speed of 4 ms -1 and the remaining half at a speed of 6 ms -1 . what is the average speed of the bus.

Answer 1

Here,

v₁ = 4 m/s and v₂ = 6 m/s

Since, the distance covered by the bus is same for 1st half and 2nd half.

So, d₁ = d₂

Thus, Average speed = 2 (4 ₓ 6)/(4 + 6) = 2 ₓ 24 / 10 = 4.8 m/s

Answer 2

Answer:

5m/s

Explanation:

4+6/2=10/2

=5m/s
