A plane traveled for a total of 1,190 miles over the course of 5 hours. Heading east, the plane traveled at an average speed of
266 miles per hour, and heading north, it traveled at an average speed of 196 miles per hour. For how many hours was the plane heading east?
1 answer:
Two equations are:
Te is time east
Tn is time north
Te + Tn = 5 hours
266Te +196Tn = 1190 is the distance equation
Solve these two equations and
Te = 3 hours and Tn= 2 hours
