Question

At 1:00 P.M., oil begins leaking from a tank at a rate of (6 0.77t) gallons per hour. (Round your answers to three decimal places.) (a) How much oil is lost from 1:00 P.M. to 4:00 P.M.

Answer 1

`Amount = 8.31`

Explanation:

Given

`Rate = 6 + 0.77t`

Required

Determine the gallons of oil lost between 1pm to 4pm

`Rate = 6 + 0.77t`

Where t represents number of hours

First, we need to calculate the duration between 1pm and 4m.

`t = 4pm - 1pm`

`t = 3\ hours`

Substitute 3 for t in
`Rate = 6 + 0.77t`

`Amount = 6 + 0.77 * 3`

`Amount = 6 + 2.31`

`Amount = 8.31`

Hence, 8.31 gallons of oil has been lost
