The own speed of the ship is 40.5 km / h and the speed of the current is 5.8 / h. Find the speed of the ship upstream and upstream.
1) What is the speed of the ship downstream?
Since the motor ship goes downstream faster, therefore, the speed of the motor ship and the current speed must be added.
40.5 + 5.8 = 46.3 km / h.
2) What is the speed of the ship against the current?
The motor ship moves more slowly against the current, therefore, it is necessary to subtract the current speed from the motor ship’s own speed.
40.5 – 5.8 = 34.7 km / h.
Answer: the speed of the motor ship downstream is 46.3 km / h, and upstream is 34.7 km / h.
