A ship traveled at an average rate of 22 miles per hour going west. It then traveled at an average rate of 12 miles per hour heading north. If the ship traveled a total of 158 miles in 9 hours, how many miles were traveled heading north?
Tw = Time traveled west Tn = Time traveled north Tw + Tn = 9 hours 22Tw + 12Tn = 158 miles Solve the 2 equations and you get Tw = 5 hours Tn = 4 hours 12 x 4 = 48 miles traveled north
