Aaron's plane flew 3.21 meters further than Noah's plane.
Explanation
Aaron's plane flew 4 meters and Noah's plane flew 79 centimeters.
So, first we need to convert 79 centimeters into meters.
We know that, 1 centimeter = 0.01 meter
So, 79 centimeters = [tex](0.01*79)meter= 0.79 meter[/tex]
Now, the difference of distance between Aaron's plane and Noah's plane is [tex](4-0.79) meters = 3.21 meters[/tex]
