• Another way you will see this type of problem:

Elapsed Time

Strategies for Elapsed Time

• Use a clock in the room.

• Draw a timeline.

• Add and subtract time, but remember to regroup using 60 minutes in an hour.

Using Area and Elapsed Time

Some questions will give you a surface area that is a fraction of a bigger area. They will give you a time that it will take for the original surface area and ask you to calculate or estimate the time to “finish” the remaining area.

Does this look familiar? Willie was hanging wallpaper on the

south wall in his living room. It took him 20 minutes to cover this much of the wall. About how long will it take for Willie to finish the wall? About how long will it take Willie to wallpaper the entire wall?
