Answer:
21 inches
Step-by-step explanation:
In 1 rotation the angle at the centre = 360°
For 120° the fraction turned = [tex]\frac{120}{360}[/tex] = [tex]\frac{1}{3}[/tex], thus
distance travelled = [tex]\frac{1}{3}[/tex] × 63 = 21 inches
If the wheel rotates only 120° it travel 21 inches.
The angle at the center of one rotation is 360°.
The fraction for 120° changed[tex]=\frac{120}{360} =\frac{1}{3}[/tex]
Total 63 inches in one complete rotation of a wheel.
Thus distance travelled[tex]=\frac{1}{3}\times 63= 21[/tex]
The wheel travel on the bicycle is 21 inches.
