Question

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

Answer 1

-1140 ft

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.

Answer 2

She went down 1140 ft

-1140 ft

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
