plane can fly 1020 miles in the same time as it takes a car to go 360 miles. If the car travels 110 mph slower than the plane, find the speed of the plane.

Solution

Solution

plan e^{'} s speed : 170

Solution steps

Translate the problem into an equation:

\frac{1020}{x} = \frac{360}{x - 110}

Solve for

x, \frac{1020}{x} = \frac{360}{x - 110} : x = 170

plan e^{'} s speed : 170
