A car with a $20-$gallon gas tank averages $21\mathrm{.}5$ miles per gallon when driven in town and $26\mathrm{.}8$ miles per gallon when driven on the highway. Write a program that calculates and displays the distance the car can travel on one tank of gas when driven in town and when driven on the highway.

Hint: The following formula can be used to calculate the distance:

Distance$=$Number of Gallons x Average Miles Per Gallon.
