While returning to the glider port, Laura descended at a rate of 380 feet per minute for 3 minutes. Calculate her change in altitude.

-1140 ft

Step-by-step explanation:

distance = rate times time.

Therefore, in this case,

change in altitude = descent = rate times time

= (-380 ft/min) (3 min) = - 1140

The glider descended 1140 ft.

She went down 1140 ft

-1140 ft

Step-by-step explanation:

Change in altitude will be negative since she is descending

Take the rate and multiply by the time to determine how many feet she is going down

-380 ft / 1 minute * 3 minutes

-1140 ft

She went down 1140 ft

-1140 ft
