An oil company fills 1/12 of a tank in 1/3 hour. At this rate, which expression can be used to determine how long will it take for the tank to fill completely? a. 1/12 x 3 hours
b. 1/3 x 12 hours
c. 1/3 x 1/12 hour
d. 3 x 12 hours

Answers

Selection B is appropriate.

_____
It takes 12 times as long to fill the whole tank as it does to fill 1/12 of the tank.
.. 12 * (1/3 hour) = (1/3)*12 hour

Answer: b . $(1)/(3)*12$ hours

Step-by-step explanation:

Given : A oil company fills $(1)/(12)$ of a tank in $(1)/(3)$ hour.

i.e. Time taken to fill $(1)/(12)$ of a tank= $(1)/(3)$ hour.

By using the Unitary method, we multiply 12 on bith the sides of the above expression we get

Time taken to fill $(1)/(12)*12$ tank= $(1)/(3)*12$ hour.

⇒ Time taken to fill 1 tank= $(1)/(3)*12=4$ hour.

Hence, it will take $(1)/(3)*12$ hours or 4 hours for the tank to fill completely.

Thus , the correct answer is b . $(1)/(3)*12$ hours

gas, Write a function d(x), that gives the distance the Escape can travel with x gallons of gas in
the tank.

Answers

Given :

Maximum capacity of fuel tank , M = 14 gallon .

It can travel approximately 26 miles with one gallon of gas.

To Find :

A function d(x), that gives the distance the Escape can travel with x gallons of gas in the tank.

Solution :

Car can travel 26 miles in one gallon of gas.

So , distance covered in x gallon of gas :

$D(x)=26x$

( Here, 0 ≤ x ≤ 14 ) or x ∈ [ 0 , 14 ] .

Hence , this is the required solution.
