Problema Solution
A plane can fly 870 miles in the same time it takes a car to drive 270 miles. how fast are the car and plane moving if the plane flies 100 miles per hour faster than the car?
Answer provided by our tutors
Let 'v' represent the speed of the car then the speed of the plane is 100+v.
Since speed = distance/time follows time = distance/speed:
870/(100 + v) = 270/v

........
v = 45 mph
100 + 45 = 145 mph
The speed of the car is 45 mph.
The speed of the plane is 145 mph.
