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

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

-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.

2/3 or 66.66..%

Step-by-step explanation:

First, add all the number of marbles and you get 6. Second you just divide the number of green marbles which is 4 by 6 and you get 2/3 or if they want it in percent then, 66.66..%
