<span>Let us first find a ratio between the quantity of work done by Darnell and Julius. If Darnell does one part of the work, Julius does two parts of the work. That is, their work quantity ratio is 1:2. (Total 3 parts) In other words when Darnell does 1/3 of the work, Julius does 2/3 of the work.
When they work together, the work is completed in 4 hours. 4 hours work is the combined output of 1/3 by Darnell and 2/3 by Julius. If Julius was not there, Darnell would have to work for more than 4 hours.
We already know that Darnell does only 1/3 of a work during any given time. If the given time is 4 hours, how many one-thirds will Darnell require? To find the answer, divide the given number (4 hours in this case) by the given fraction( 1/3 in this case) To divide a number by a fraction, multiply the number by the reciprocal of the fraction. Thus it becomes 4 divided by 1/3 = 4 x 3/1 = 12.
(Another hint: At the rate of 1/3 of a work in one hour, Darnell will needs 3 hours to complete the given task. If the given work is 4 hours long, Darnell will take 4 x 3 hours, that is 12 hours.)</span>

Answer:
$90.
Step-by-step explanation:
We have been given that Philip is going on a 4000 kilometer road trip with three friends. The car consumes 6 liters of gas per 100 kilometers.
Let us find how many liters the car will consume per kilometer.
![\text{Gas consumption by car per kilometer}=\frac{6\text{ liters}}{100\text{ km}}](https://tex.z-dn.net/?f=%5Ctext%7BGas%20consumption%20by%20car%20per%20kilometer%7D%3D%5Cfrac%7B6%5Ctext%7B%20liters%7D%7D%7B100%5Ctext%7B%20km%7D%7D)
Now let us find total consumption of gas for the whole trip.
![\text{Gas consumption by car for the whole trip}=4000\text{ km}*0.06\frac{\text{ liters}}{\text{ km}}](https://tex.z-dn.net/?f=%5Ctext%7BGas%20consumption%20by%20car%20for%20the%20whole%20trip%7D%3D4000%5Ctext%7B%20km%7D%2A0.06%5Cfrac%7B%5Ctext%7B%20liters%7D%7D%7B%5Ctext%7B%20km%7D%7D)
![\text{Gas consumption by car for the whole trip}=240\text{ liters}](https://tex.z-dn.net/?f=%5Ctext%7BGas%20consumption%20by%20car%20for%20the%20whole%20trip%7D%3D240%5Ctext%7B%20liters%7D)
Now let us find total cost of gas for whole trip by multiplying the number of liters gas consumed in whole trip by cost of one liter of gas.
![\text{The total cost of gas for whole trip}=240\text{ liters}*1.50(\frac{Dollars}{\text{liter}})](https://tex.z-dn.net/?f=%5Ctext%7BThe%20total%20cost%20of%20gas%20for%20whole%20trip%7D%3D240%5Ctext%7B%20liters%7D%2A1.50%28%5Cfrac%7BDollars%7D%7B%5Ctext%7Bliter%7D%7D%29)
![\text{The total cost of gas for whole trip}=360\text{ Dollars}](https://tex.z-dn.net/?f=%5Ctext%7BThe%20total%20cost%20of%20gas%20for%20whole%20trip%7D%3D360%5Ctext%7B%20Dollars%7D)
Philip and his 3 friends has gone for the road trip, so the total number of people gone for road trip will be 4.
![\text{Each person will pay}=\frac{360}{4}](https://tex.z-dn.net/?f=%5Ctext%7BEach%20person%20will%20pay%7D%3D%5Cfrac%7B360%7D%7B4%7D)
Therefore, each person will have to pay $90 to split the cost of gas evenly.
