Question

Mattie Evans drove 150 miles in the same amount of time that it took a turbopropeller plane to travel 750 miles. The speed of the plane was 200 mph faster than the speed of the car. Find the speed of the plane.

Answer 1

p= 200+ c

d=rt

t=d/r

150/c = 750/p = 750/(200+c)

1/c =5/(200+c)

200+c=5c

4c=200

c=200/4 = 50 mph

p= 250 mph

each traveled for 3 hours
