Arunner completed a 26.2 mile marathon in 210 minutes.
estimate the unit rate in miles per minute
estimate the unit rate in minutes per mile.

The unit rate in minutes per miles be 8.02 minutes per miles .

Step-by-step explanation:

As given

A runner completed a 26.2 mile marathon in 210 minutes.

i.e

26.2 miles = 210 minutes

Now calculate the  unit rate in minutes per mile.

Putting the value

Therefore the unit rate in minutes per miles be 8.02 minutes per miles .

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
