The boat covered the distance at a speed of 40 km / h in 4 hours.
Distance = speed * time (S = U1 * t1)
S = 40 * 4 = 160 (km) – the distance that the boat traveled there.
And to find the speed on the way back, you need to divide the distance (it has not changed) by the inverse time.
U2 = S / t2 = 160/5 = 32 (km / h) – speed on the way back.
Answer: 32 km / h
