The boat’s own speed is 26 km / h, the current speed is 3.5 km / h. the boat sailed up the river for 4 hours.

The boat’s own speed is 26 km / h, the current speed is 3.5 km / h. the boat sailed up the river for 4 hours. which way of the boat – up the river or down the river more and how much?

1. Let’s find the speed of the boat up the river:

26 – 3.5 = 22.5 (km / h).

2. Let’s calculate the speed of the boat down the river:

26 + 3.5 = 29.5 (km / h).

3. Let’s calculate the distance covered by the boat up the river in 4 hours:

22.5 x 4 = 90 (km).

4. Let’s find the path traversed by the boat down the river in 4 hours:

29.5 x 4 = 118 (km).

5. Let’s calculate how much longer is the path along the river downstream than upstream:

118 – 90 = 28 (km).

Answer: the path of the boat down the river is more than 28 km up.
