The boat’s own speed is 8 km / h, and the current speed is 1.3 km / h. how far will the boat

The boat’s own speed is 8 km / h, and the current speed is 1.3 km / h. how far will the boat go downstream in 3.5 hours? how far the boat will cover against the current in 5.6 hours.

1. Let’s find at what speed the boat sails along the river per hour.

8 + 1.3 = 9.3 kilometers.

2. Determine what distance the boat will go downstream in 3.5 hours.

3.5 * 9.3 = 32.55 kilometers.

3. Let’s calculate the speed of the boat against the current.

8 – 1.3 = 6.7 kilometers.

4. We find the traversed path by the boat against the river flow in 5.6 hours.

6.7 * 5.6 = 37.52 kilometers.

Answer: In 3.5 hours the boat will cover 32.55 kilometers along the river, and in 5.6 hours against the river it will cover 37.52 kilometers.
