Science-How much energy is that anyway?

Question

if you travel 10 miles to school each day and your car gets 24 miles per gallon of gas.how many gallons of gas did you burn in order to get to school.

Answer 1

You have a distance (10 miles) and a rate (24 miles/gallon). The rate can be flipped over to say (1 gallon/[24 miles]). Multiply the distance by the rate to get [10 miles]*[1 gallon/(24 miles)]=10 miles*gallon/(24 miles). The 'miles' in the numerator and denominator cancel, and you're left with 10/24 gallons, which simplifies to 5/12 gallon or about 0.417 gallon.
