Solve the equation if an aeroplane leaves a point on a latitude 55 at12 noon. If it flies due south at a steady speed of 600 km what is it's latitude at 2 pm

2 answers

distance = speed * time = 600*2 = 1200km
how many km in a degree of latitude? (2πR/360)
so divide by that to get the degrees traveled, and subtract from 55N (or add, if it's 55S)
Simple solution:
Flying at 600 km/h for 2 hours results in a distance of 1200 km
Each degree of latitude is approximately 111 km apart, and since
1200/111 = 10.81
the latitude is appr 55-10.81 or 44.2°
