A car moves a distance of 200 m. It covers the first half of the distance at speed 40 km/hr and second half of distance at speed v. The average speed is 48 km/hr. Find the value of v?

We have,

Distance moved, s = 2 km

Velocity, u1 = 40 km/hr

u2 = v

Average velocity = On solving the equation, we get

v = 60 km/hr
