An astronaut is returning to Earth in a spacecraft. If the spacecraft is descending at a rate of 13.81 kilometers per minute, what will its change in height after 5 1/2 minutes?
the astronaut is descending 13.81km each minute, so multiply that by 5 and a half minutes you get 75.955. Since he is going down, his height will change by a negative 75.955 instead of a positive one.
