A military jet flies directly over and at a right angles to the straight line course of a commercial jet. The military jet is flying 200 mph faster than four times the commercial jet. How fast is each going if they are 2050 miles apart (on a straight line) after one hour?

C=speed of commercial jet in mph
M=speed of military jet
=4C+200 mph
Distance after one hour, using Pythagoras theorem
=√(C²+M²)=2050
Solve for C and M
