Question

an airplane takes off 12.5 miles south of a city and flies due north at a constant speed of 170 miles per hour. What is the plane's position relative to the city after 45 minutes.

Answer 1

75 miles/hr* (45/60) hours=56.25. Initial position is -12.5. Add -12.5 to 56.25 which results in 43.75 miles due north.
