Question

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

1
4
x.

How far will the plane fly in 28 minutes?
A) 112 miles
B) 116 miles
C) 120 miles
D) 124 miles

Answer 1

A)112 miles

Explanation:

The plane will fly 112 miles in 28 minutes.

y =

x → 112 = x

Answer 2

(A) 112 miles

Explanation:

The plane flies 48 miles in 12 minutes. First, find out the amount of miles flown in 1 minute, by simplifying the fraction:

(48 miles)/(12 minutes) = (4 miles)/(1 minute)

The plane flies 4 miles every minute.

Now solve for the amount of area that plane covers in 28 minutes. Multiply 28 with 4:

4 x 28 = 112

(A) 112 miles is your answer.
