Aplane 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.

170 mph

Step-by-step explanation:

Let x mph be the plane's speed.

If the car travels 110 mph slower than the plane, then the car's speed is x - 110 mph.

Plane:

Speed = x mph

Distance = 1,020 miles

Time = t hours

Car:

Speed = x - 110 mph

Distance = 360 miles

Time = t hours

A plane can fly 1020 miles in the same time as it takes a car to go 360 miles, so

Cross multiply:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
