<u>The airplane flies:</u>
200 miles per hr
400 miles per hr
600 miles per hr
Average speed = Total distance ÷ total time
= (200 + 400 + 600)miles ÷ 3hrs = 400miles/hr
Time = Distance ÷ Average speed
= 2000miles ÷ 400miles/hr = 5hrs

Answer:
3. The first equation can be multiplied by 3 and the second equation by 2.
Step-by-step explanation:
2 x + 3 y = 25 (1)
-3 x + 4 y = 22 (2)
Multiply equation (1) by 3 and (2) by 2.
3(2x) = 6x
2(-3x) = -6x
When you add the two equations, x will get cancelled last
