A plane was sighted over two different observation posts that were 650 miles apart. The plane passed over the first post at 4:00 A. M. and over the second post at 6:30 A. M. At what speed was the plane traveling.

260 mph

Step-by-step explanation:

With the information given, we know the plane traveled 650 miles in 2.5 hours

To find the speed, do distance/time

650 ÷ 2.5 = 260

= 260 mph

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
