Answer:

106

Step-by-step explanation:

The diameter of the wheel is 15 cm or 0.15 m.

The circumference of the wheel is 0.15π m ≈ 0.47 m.

So the wheel moves 0.47 m with each revolution.

The wheel travels 50 m, so the number of revolutions is:

(50 m) / (0.47 m/rev) ≈ 106 revolutions.

The greatest difference you can get is 42

The range of the integer is given as:

Smallest = -16

Largest = 26

So, the range is calculated as:

Range = Largest - Smallest

Substitute known values

Range = 26 - (-16)

Evaluate the difference

Range = 42

Hence, the greatest difference you can get is 42
