technology and invention gps vs. compass


What did we find out?

It took the GPS team 3 hours and 11 minutes to get through the whole hike. The map and compass team took only 2 hours and 49 minutes. The biggest problem the GPS team encountered was that they lost the satellite signal in some areas. With no map or compass, they had to wander around until they were in an area where the signal was good.
