How much will it take to do a work of 190J with 15w power

Step-by-step explanation:

Solve for t.

Multiply both sides by t.

Divide both sides by 15.

Calculate the time ?

We know,

Substituting the values of work and power, we get:

Thus,the time taken by a body is 12.66 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

sorry can't
