The change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.
Given that a weather balloon is descending from the atmosphere, and its altitude changes by -6 meters every second, to determine what is the change in altitude after 135 seconds the following calculation must be performed:
- Amount of time x change per second = total change
- 135 x (-6) = X
- -810 = X
Thus, the change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.

Find the change
the change is 63-21=42
42 degrees in 12 hours
we want to find xdegrees/1hour
42/12=3.5 degrees per hour
