Question

A man runs from a place A to a place B in 1 hour 30 minutes . If the distance between the two places is 6 km , find his speed .

Answer 1

Given, Time taken to cover distance between place A & B = 1 hour 30 min = $1+\frac{1}{2}=\frac{3}{2}$ hour

Distance between A & B = 6 cm

Now speed of man = $\frac{Distance}{time}=\frac{6}{3/2}=\frac{2\times 6}{3}$

[speed = 4 km/h]
