1) A research team is planning to use an ice drill at the top of a glacier. The team plans to use the drill for 10 hours each day while the temperature is warmest. The drill's position will move 5 1/12 feet every hour it is used. Predict the change in the drill's position each day. Begin by making an estimate. About how much does the drill's position change in one day?
--65 feet
-50 feet
-5 feet
-2 feet
