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
