a boat starts at point a p travels 15 miles due north to point r then turns due east and travels 8 more miles to the dock at point t
find the distance the boat would have traveled if it had gone directly from point p to point t

math 
JJ,
This is a right triangle problem.
c^2 = a^2 + b^2
c^2 = 8^2 + 15^2
remember to take the square root in the last step to find c.
