Merry is a trucker and needs to keep track of her mileage for business purposes. She begins a trip with an odometer reading of r miles and ends the trip with an odometer reading of t miles.
\n" ); document.write( " a. Express the total of miles covered algebraically.
\n" ); document.write( "Ans: t-r miles
\n" ); document.write( "----------------------
\n" ); document.write( "b. If the tip takes h hours of driving, express the average speed algebraically.
\n" ); document.write( "Ans: (t-r)/h miles/hour
\n" ); document.write( "-----------------------
\n" ); document.write( "c. If the truck used g gallons of gas during the trip, express the mpg the truck averaged during the trip algebraically.
\n" ); document.write( "Ans: [(t-r)/g] miles/gallon
