Suppose a driver is traveling from one city to another. A diagram is given to help with the first two questions. Create additional diagrams as needed. Be prepared to explain your reasoning.

1. The distance between the cities is 60 miles, and the driver has driven of the way.
   1. How many miles has she driven?
   2. How many miles remain?
2. Later, the driver has driven of the way.
   1. How many miles has she driven?
   2. How many miles remain?
3. On a different trip, the distance between the cities is 300 miles, and she has driven of the way.
   1. How many miles has she driven?
   2. How many miles remain?
4. A trip is miles long, and the driver has gone of the way. Write an expression to represent how many miles remain in her trip.
