Aircraft A and aircraft B are 720 miles apart and move towards each other. The speed of aircraft A is 114 mph and the speed of aircraft B is 366 mph. Where will both aircraft meet (distance from the startpoint of aircraft A)?

where and how?
thanks in advance
 
Distance betwen them is given by
720 - (114+366)t
If they meet distance is zero so
720 - (114+366)t = 0
t = 1.5hrs

This time corresponds to 114*1.5 = 171miles from A's starting position.
