Answer:
18 Minutes
Step-by-step explanation:
Simon and sophie each do a fraction of the job per minute like this:
-Simon does 
per minute (if we multiply this by 30 we have the completed job)
-Sophie does 
of the job per minute (again if we multiply this by 45 we have the completed job)
We will add this two to know how much of the job they do together in a minute:
They will do 
of the job per minute.
So the total time will be when they do 
, we can put this in one equation like this:
where x is the total times we need to do of the job to complete it. We solve for x:
<h3>
Answer: 54 gallons</h3>
Work Shown:
(distance)/(gallons used) = (distance)/(gallons used)
(333 miles)/(37 gallons) = (486 miles)/(x gallons)
333/37 = 486/x
333x = 37*486 .... cross multiplication
333x = 17,982
x = (17,982)/333
x = 54 gallons
You need 54 gallons to travel 486 miles.
