Hi Eliz,

Thanks for writing to Dr. Math.

The "reciprocal rate" refers to the reverse of the units. So if for
your problem you are given that a car gets so many miles for every
gallon, the reciprocal rate is how many gallons it takes to go one
mile.

I hope this hint helps. If you'd like a little more help calculating
