<PRE><B>Question 739854</B>
Uniform rates application.  Rate is fuel efficiency in miles per gallon of fuel.  If rate is r, v is volume or gallons of fuel, d is distance in miles, then we can use {{{r*v=d}}}.


Let m = gallons of fuel first car used
Let n = gallons of fuel second car used


Car___________rate____________volume_____________distance
First_________25______________m__________________25m
Second________35______________n__________________35n
TOTAL_________________________65________________1975


Can you find the two equations to create for a system, and then solve the equation system for m and n?  </PRE>
