Suppose a plane flies 48 miles in 12 minutes. The relationship between miles flown, x, and minutes flown, y, by the plane can represented by the equation y = 1/4

Question

x.

How far will the plane fly in 28 minutes?

Answer 1

To find how far the plane will fly in 28 minutes, we can use the equation y = 1/4 x, where x represents the distance flown in miles and y represents the time flown in minutes.

We know that the plane flew 48 miles in 12 minutes, so we can plug in those values to find the proportionality constant, k:

y = 1/4 x
12 = 1/4 * 48
k = 12

Now we can use the equation to find how far the plane will fly in 28 minutes:

y = 1/4 x
28 = 1/4 x
x = 28 * 4
x = 112

Therefore, the plane will fly 112 miles in 28 minutes.
