Answer:

B (2, 4)

Step-by-step explanation:

A (-1,-9); M (0.5, -2.5); B (xB, yB)

M is the midpoint of AB, therefore we have these 2 equations:

(*) xA + xB = 2. xM

(**) yA + yB = 2. yM

(*) <=> xB = 2. xM - xA = 2x0.5 - (-1) = 1 + 1 = 2

(**) <=> yB = 2. yM - yA = 2x(-2.5) - (-9) = -5 + 9 = 4

So, B (2, 4)

if an airplane travels 660 mph how long will it take an airplane to travel to a distance of 2970 miles?
vazorg [7]

Answer:

4 hours and 30 minutes.

Step-by-step explanation:

660 miles = 1 hour
1320 miles = 2 hours
1980 miles = 3 hours
2640 miles = 4 hours

There are only 330 miles left and that is half of 660mph so therefore it would only take half an hour for these last 330 miles.

So we know that it will be taking 4 hours, you would then add the 30 minutes which gives you 4 hours and 30 minutes.

Hope this helps!
