3. A small airplane flew 104 miles in 50
2 answers:
Answer: The airplane can fly 124.8 miles in 1 hour.
Step-by-step explanation: Given that a small airplane flew 104 miles in 50
minutes.
We are to find the number of miles that the airplane can fly in one hour.
We will be using the UNITARY method to solve the given problem.
We have
In hours, number of miles flew by the airplane = 104 miles.
So, in 1 hour, number of miles flew by the airplane is
Thus, the airplane can fly 124.8 miles in 1 hour.

length = 126 yards and width = 44 yards
let the width = w then length = 3w - 6
perimeter = 2( length + width)
= 2( 3w - 6 + w) = 2( 4w - 6) = 8w - 12
noe perimeter = 340 hence
8w - 12 = 340
add 12 to both sides
8w = 340 + 12 = 352
divide both sides by 8 ⇒ w = = 44
thus width = 44 yards and length = ( 3 × 44) - 6 = 126 yards
