Answer:
16 inches
Step-by-step explanation:
<em>Note: it should say 56π inches instead of 56 inches otherwise no option is correct</em>
<u>Given</u>
- Diameter of the wheel = 16 in
<u>Full circumference of the wheel </u>
<u>Bike moves </u>
<u>The wheel turns:</u>
We only consider her 0.5 of full turn of the wheel to identify the screw position
Since we consider the turns from the ground level as the initial position of the screw, the screw position in the end will be half turn opposite to ground level.
This is the full diameter length, which is 16 inches
So correct answer option is 16 inches
15x = 3x + 120 (subtract both sides by 3x)
12x = 120 (divide both sides by 12)
x = 100
