x.

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

Answer 1

Answer:

(A) 112 miles

Step-by-step 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.
