Question

An air traffic controller is plotting the course of two jets scheduled to land in 15 min. One aircraft is following a path defined by the equation 3 x - 5 y = 20 and the other by the equation 18x = 30y + 72. Should the controller alter the paths of either aircraft? Justify your decision.

Answer 1

3x-5y=20

multiply by 6

18x-30y =120

18x-30y = 72

the 2 paths never intersect, they are parallel

but if 72 and 120 are inches and the jets wider than 120-72= 48 inches= 4 feet, they may collide
