Question 943440: From a point on a river, two boats are driven in opposite directions, one at 8 miles per hour and the other at 5 miles per hour. In how many hours wil they be 39 miles apart? Answer by amarjeeth123(570) (Show Source):
You can put this solution on YOUR website! Let the number of hours be x.
Distance traveled by the first boat=8x
Distance traveled by the second boat=5x
Total distance=8x+5x=13x
Total distance=39 miles
13x=39
x=3 hours
In 3 hours they will be 39 miles apart.
