A motor boat travels 180 miles in 5 hours going upstream. It travels 260 miles going down stream in the same amount of time. What is the rate of the boat in still water a and what is the rate of the current .
+36916 180 m / 5 hr = B - C or 180 = 5B - 5C
260 m/ 5 hr = B + C or 260 = 5B + 5C
Add the two red equations to solve for 'B' ..... you should be able to solve for 'C' from there.....
