Troy was trying to catch up with the rest of his group, who had left earlier on a kayaking trip. troy paddled 8 hours downstream, covering 72 miles before realizing that he had passed his group’s campground. he had to paddle back upstream for 18 miles to get back to his group’s campground. if the trip back upstream took troy 6 hours, how fast was the river flowing (in mph)?

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
