Question 1157807: Two fishing boats leave Sandy Cove at the same time traveling in the same direction. One boat is traveling 3 times as fast as the other boat. After 5 hours the faster boat is 80 miles ahead of the slower boat. What is the speed of each boat.
Velocities (rates of traveling) x and 3x miles per hour.
Equation
5*(3x) - 5*x = 80 miles
Simplify and solve
15x - 5x = 80
10x = 80
x = 80/10 = 8.
ANSWER. 8 mph and 24 mph.
