A boat traveled 175 miles each way downstream and back. The trip downstream took 7 hours. The trip back took 35 hours. What is the speed of the boat in still water? What is the speed of the current?

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

5   1/4   miles per hour
