A plane can fly 650 miles in the same time as it takes a car to go 200 miles. If the car travels 90 mph slower than the plane, find the speed of the plane.

Solución

Solución

plan e^{'} s speed : 130

Pasos de solución

Translate the problem into an equation:

\frac{650}{x} = \frac{200}{x - 90}

Resolver para

x, \frac{650}{x} = \frac{200}{x - 90} : x = 130

plan e^{'} s speed : 130
