Real-Life Math

You are a backhoe operator digging a ditch in an urban area. Maneuvering the machine around the various lampposts, fire hydrants and parked cars can be difficult.

"When you're operating the equipment, you need to measure how deep to dig a hole, how much to grade and figure out how long it might take you to dig a hole," says Ron O'Connor. He is a heavy equipment operator. "If you get into running your own business, you will use math skills a lot."

In order to make the job easier, you want to minimize the amount of times you will have to move your backhoe in order to dig the trench. The scooping arm of your backhoe has a 15-foot extension. This means you can dig 15 feet of trench from one spot.

You need to dig a trench that is 60 feet long. You have positioned the machine so that you can dig the first 15 feet. How many more times will you have to move the machine to dig the rest of the trench?
