Question 1188548: A boat travels 180 miles downstream in six hours. The return trip, going upstream the same distance, took ten hours. Find the amount of time the boat would require to make the 180-mile trip without a current. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! A boat travels 180 miles downstream in six hours. The return trip, going upstream the same distance, took ten hours. Find the amount of time the boat would require to make the 180-mile trip without a current.
-----------------
The boat's "groundspeed" downstream is 180/6 = 30 mi/hr
Upstream is 180/10 = 18 mi/hr
---
The boat's "waterspeed" is the average = (30+18)/2 = 24 mi/hr
---
180/24 = 7.5 hours
