Problema Solution
At a given hour, two steamboats leave a city in the same direction on a straight canal. One travels at 18 mph and the other travels at 25 mph. In how many hours will the boats be at 35 mi apart ?
Answer provided by our tutors
Path of 18 mph boat: 18t, where t is in hours.
Path of 25 mph boat: 25t
Difference in distance: 25t - 18t = 7t
Solve for 7t = 35;
t = 5
The boats will be 35 miles apart after 5 hours.
