Question

3. A cyclist rides his cycle with a speed of 30 m/s for the first half and the next half-
length he covers with a speed of 45 m/s. Find the average speed of the cyclist.

Answer 1

Answer:

36 m/s

Explanation:

Let us say that the total distance is 2x.

Then, Total time = x/30 + x/45 = 3x/90 + 2x/90 = 5x/90 = x/18

Average Speed = 2x ÷ x/18 = 2x × 18/x = 36 m/s
