on the Glacier!
There are a few people here at Palmer Station who like to go out to ski on the glacier behind the station. Maggie Amsler is one of those skiers. She usually goes out at 0530 and skis for an hour. In order to go out there, Maggie signs out on the board, so people know where she is. She signs herself out from 0530-0700, but she is usually back in one hour.
Maggie was interested in knowing what the rate of incline was for the separate stages of the ski trail. She borrowed the GPS (Global Positioning Satellite) monitor in order to take her measurements. The GPS recorded that she started from the bottom level of the Biology Lab at an elevation of 30 meters. We know that isn't possible, because the second floor of the building is at an elevation of 26 feet! Anyway, the rate of change between the elevation measurements is the important number. Using this information that Maggie collected, what is the slope of each section of the trail to the top? What is the total change. Can you graph this?
