Question

A motorist is pumping gas into his car at a rate of 5/12 of a gallon every 1/24 of a minute. At this rate, how many gallons of gas will he have pumped into his car in 1/2 of a minute?

Answer 1

5/12 × 12 = 60/12 = 5 is to 0/12 = 5 gallons

Answer 2

In  $\frac{1}{2}$ of a minute gas will he have pumped into his car = 5 gallon.

Given:

A motorist is pumping gas into his car at a rate of 5/12 of a gallon every

$\frac{1}{24}$ of a minute.

To find:

At this rate, how many gallons of gas will he have pumped into his car in

$\frac{1}{2}$ of a minute?

Explanation:

1 minute = 60 second.

So, $\frac{1}{24}$ of a minute = $\frac{1}{24}$ × 60 = 2.5 sec.

       $\frac{1}{2}$ of a minute = $\frac{1}{2}$ × 60 = 30 sec.

For 2.5 sec  5/12 of a gallon

For 30 sec = "x" of a gallon

Cross multiplication,

2.5 × x = 30 ×$\frac{5}{12}$

        x = 5 gallon.

In  $\frac{1}{2}$ of a minute gas will he have pumped into his car = 5 gallon.
