The speed of the boat downstream is 18.4 km / h, the speed of the current is 1.6 km / h.

The speed of the boat downstream is 18.4 km / h, the speed of the current is 1.6 km / h. How far will the boat cover upstream in 2.5 hours?

First, we determine the boat’s own speed.

We subtract the current velocity from the downstream velocity.

18.4 – 1.6 = 16.8 km / h.

Find the speed of the boat in the indicated direction.

We subtract the current velocity from the obtained value.

16.8 – 16 = 15.2 km / h.

We find the distance traveled.

We multiply 15.2 km / h by time.

15.2 * 2.5 = 38 km.

Answer: The boat will cover 38 km against the current in 2.5 hours.
