Problema Solution
During the first part of a trip a canoeist travels 49 miles at a certain speed. The canoeist travels 3 miles on the second part of the trip at a speed 5 mph slower. The total time for the trip 4 hrs. What was the speed on each part of the trip?
Answer provided by our tutors
The speed in first part: x
The speed in second part: (x-5)
So the equation is
49/x + 3/(x-5) = 4
So
x = 13.44
So
The speed in first part: 13.44 mph
The speed in second part: 8.44 mph
