Idk if this wil help but...
Let speed of Matthew be X yards/min Speed of Lowe = 3X yards/min.
Distance covered by Matthew in 30 minutes = 30X
Distance covered by Lowe in 30 minutes = 30(3X)= 90X
90X = 30X + 1200 X = 20 yards/min
Let speed of Matthew be X yards/min Speed of Lowe = 3X yards/min.

90X = 30X + 1200 X = 20 yards/min
4+x=18, the sum would make it an addition problem and x would represent "a number".

The circumference of a circle is C=2πR, where R is the radius of the circle and π≈3.14.
So if we open the circumference of the circle into a straight line segment, the length of this segment is C=2πR≈2*3.14*R=6.28R
4 rotations mean 4 circumferences that is 4 segments of length 6.28R,
which makes a linear distance of 4*6.28R=25.12R
i: the radius of the smaller wheel is R=r, thus it covers a distance of 25.12r feet
ii: the radius of the smaller wheel is R=2r, thus it covers a distance of 25.12*2r=50.24r (feet)
50.24r is twice 25.12r, thus the larger wheel traveled Twice the distance of the smaller one.
Answer: the larger covered twice the distance of the smaller.
