Pratap puri rowed 14 miles down a river in 2 hours, but the return trip took him 3 and one half hours. find the rate pratap can row in still water and find the rate of the current. let x equals rate pratap can row in still water and y equals rate of the current. what is the rate that pratap rows in still water?

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
