Question

A tanker truck fills the gas station's reservoir at the rate of 1212 gallons per minute. If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir? Round your answer to the nearest tenth. Enter your answer in the box.

Answer 1

Answer:

2.9 minutes

Step-by-step explanation:

Given

$Rate = 12 gallon/minute$

$Size = 35\ gallon$

Required

Determine the time spent

The rate is a ratio of size to time

So, it can be expressed as:

$Rate = \frac{Size}{Time}$

Substitute values for Rate and Size

$12 = \frac{35}{Time}$

Cross Multiply

$12 * Time = 35$

Solve for Time

$Time = 35/12$

$Time = 2.9$ (approximated)
