A construction crew built 9 3/4 miles of road in 4 1/2 days. What is the unit rate in miles per day

2⅙ miles per day

Step-by-step explanation:

Miles : Days

39/4 = 9¾ : 4½ = 9/2

X : 1

39/4 ÷ 9/2 = X/1

39/4 × 2/9 = X

13/6 = X

X = 2⅙

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
