Answer:
0.5 + 0.06 + 0.004 in expanded form.
Step-by-step explanation:
The speed of plane 1 will be 300 miles/sec and that of plane 2 will be 600 miles/sec.
We have two planes flying in opposite directions to each other.
We have to determine how fast was the each plane flying.
<h3>What is the formula to calculate the distance covered by the object moving with speed - x m/s in time - t s ?</h3>
The formula to calculate the distance travelled will be -
distance = speed x time = (
t) meters
According to the question -
Let us assume that the speed of plane 1 = v miles/sec.
Then, the speed of plane 2 will be = 2v miles/sec.
Distance covered by plane 1 in 3 hours will be = 3v miles.
Distance covered by plane 2 in 3 hours will be = 3 x (2v) miles = 6v miles.
Since they are 2700 miles apart after three hours, therefore -
3v + 6v = 2700
9v = 2700
v = 300 miles/sec
Hence, the speed of plane 1 will be 300 miles/sec and that of plane 2 will be = 2v = 2 x 300 = 600 miles/sec.

Answer:
The y-intercept is 3.
Step-by-step explanation:
I had to use a graph but if you mark the point on the graph. The slope is 2 so you would go up 2 right 1. But you can also do it the opposite way, go down 2 left 1. I hope this helps!
