LESSON 13 Solving Distance Problems
The basic formula for solving distance problems is distance¼ratetime
orD¼RT. For example, if an automobile travels at 30 miles per hour for
2 hours, then the distance isD¼RTor 30 2 ¼60 miles.
Distance problems usually involve two vehicles (i.e., automobiles, trains,
bicycles, etc.) either traveling in the same direction or in opposite directions,
or one vehicle making a round trip. The strategy for solving distance
problems is
- Draw a diagram of the situation.
- Set up a table as shown.
