Problema Solution
Mattie evans drove 250 miles in the same amount of time that it took a turbopropeller plane to travel 1150 miles. The speed of the plane was 180 mph faster than the speed of the car. what was the speed of the plane
Answer provided by our tutors
let
d1 = 250 miles the distance Mattie Evans drove
v1 = the speed of the car
d2 = 1150 mile the distance the plane traveled
v2 = the speed of the plane
The speed of the plane was 180 mph faster than the speed of the car
v2 = 180 + v1 => v1 = v2 - 180
since speed = distance/time => time = distance/speed
Mattie Evans drove 250 miles in the same amount of time that it took a turbopropeller plane to travel 1150 miles
250/v1 = 1150/v2
plug v1 = v2 - 180 into the above equation
250/(v2 - 180) = 1150/v2
by solving we find
v2 = 230 mph is the speed of the plane
