Homework Help: Word Problems

If your car gets 18 miles per gallon of gasoline, how many pints of gas will you need to take a 698- mile trip?

I no that 1pt = 480ml and 1g= 3840 ml
so do I x 18 miles per gallon by the amount of pints in a gallon?

First compute the number of gallons required, 698 mi/(18 mi/gal) = 38.78 gal

Then multiply that by 8 pints/gallon.

I get 310.2 pints

Avoid metric conversion; you just would just have to convert back again to get pints
