An air plain is flying from new york city to los angeles. the distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15t. how fast is it flying? be sure to include the units. explain. how far will it travel in 30 seconds? explain. how long will it take to go 12.75 miles? explain.

Step-by-step explanation:

1. When t=1 (second), the equation tells you the airplane travels

... d = 0.15·1 = 0.15 . . . . miles

The speed is 0.15 miles per second.

2. When t=30, the distance is given by the equation as ...

... d = 0.15·30 = 4.50 . . . . miles

3. We want to find the value of t that makes d be 12.75. Putting that number in the equation, we get ...

... 12.75 = 0.15·t

We solve this by dividing by the coefficient of t.

... 12.75/0.15 = t = 85 . . . . seconds

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

may i see the picture? it would a lot, xox
