The running club uses the money they raised to pay for a trip to a canyon. at one point during a run in the canyon, the students are at an elevation of 128 feet. after descending at a rate of 50 feet per minute, they reach an elevation of -472 feet. how long did the descent take?

12 minutes

Step-by-step explanation:

When the students start to descend at a rate of 50 feet/ mins, they were at an elevation of 128 feet.

And at the end of their descend they finally reach an elevation of - 472 feet.

So, the students descend by a depth of [128 - (- 472)] = 600 feet.

As they were descending at a rate of 50 feet/minutes.

Therefore, the descent took a time of minutes. (Answer)

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
