The own speed of the ship is 21.6 km / h. The current speed is 4.9 km / h. Find the speed of the boat upstream and upstream.
1. Let’s find the speed of the motor ship downstream, if the own speed of the motor ship is 21.6 km / h, and the speed of the current is 4.9 km / h:
21.6 + 4.9 = 26.5 (km / h).
2. Let’s find the speed against the current:
21.6 – 4.9 = 16.7 (km / h).
Answer: the speed of the ship is 26.5 km / h downstream, and 16.7 km / h upstream.
