Plane plane can fly 450 miles in the same time as it takes a car to go 180 miles. If the car travels 90 mph slower than the plane, find the speed of the plane

Answer 1

PT = 450 speed times time = distance

CT = 180

C=P-90

(P-90)T = 180

PT -90T = 180

PT = 450

90T = 270

T =3 hours

CT= 3C = 180

C = 60 mph for the car

P =150 mph for the plane
