Aplane descended at a rate of 400 feet per minute. what is the change in the elevation of the plane after 6 minutes.

The change in elevation=2,400 feet

Step-by-step explanation:

The expression to determine the change in elevation after 6 minutes is a s follows;

D=S×T

where;

D=change in elevation in feet

S=speed/ descending rate

T=time

In our case;

D=unknown

S=400 feet/minute

T=6 minutes

replacing;

D=400×6=2,400 feet

The change in elevation=2,400 feet

56

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
