The boat went 3 hours upstream and 2 hours downstream. What way did the boat go during these 5 hours

The boat went 3 hours upstream and 2 hours downstream. What way did the boat go during these 5 hours, if the boat’s own speed is 18.6 km / h, and the speed of the river flow is 1.3 km / h?

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

18.6 + 1.3 = 19.9 kilometers per hour.

2. Let’s find the speed of the boat against the stream of the river:

18.6 – 1.3 = 17.3 kilometers per hour.

3. Let’s find what path the boat covered in 3 hours, moving against the river flow:

3 * 17.3 = 51.9 kilometers.

4. Let’s find which way the boat went in 2 hours, moving along the river:

2 * 19.9 = 39.8 kilometers.

5. Let’s find which way the boat covered in 5 hours:

51.9 + 39.8 = 91.7 kilometers.
