Answer :
You have the following information:
- A boat travels 340 miles in 9 hours
In order to determine how far can the boat travel in 3 hours, you first calculate the speed of the boat. The speed is calculated by dividing 340 miles between 9 hours, as follow:
340 mi/9 h = 37.77 mi/h
Next, you multiply the previous speed by the time (3 hours):
37.77 mi/h (3 h) = 113.33 mi
Hence, the boat travles 113.33 miles in 3 hours
