1. Since when moving with the flow, the own speed of the ship increases by the speed of the current. Consequently, the speed of the ship downstream is:

40.5 + 5.8 = 46.3 km / h.

2. Since when moving against the current, the own speed of the motor ship decreases by the speed of the current. Consequently, the speed of the ship against the current is:

40.5 – 5.8 = 34.7 km / h.

Answer: 46.3 km / h and 34.7 km / h.
