Answer:
8 rotation will the tires made after frank rides 50 ft.
Step-by-step explanation:
Given: The tire on franks bike moves 75 inches in one rotation.
If bike of tire move 75 in then rotation of wheel is 1
In 75 in of tire move = 1 rotation
In 1 in of tire move = [tex]\dfrac{1}{75}[/tex] rotation
Now we change 50 ft into inches
1 ft = 12 inches
50 ft = 12 x 50 = 600 inches
In 1 inch of tire move = [tex]\dfrac{1}{75}[/tex] rotation
In 600 inch of tire move = [tex]\dfrac{1}{75}\times 600=8[/tex] rotation
Hence, 8 rotation will the tires made after frank rides 50 ft.
