Sagot :
8 rotations. first must convert 50 ft into inches. 50x12=600 in. If you know the distance and the length of rotation, divide the length (600) by the length of each rotation (75) and you get 8
Answer: 8
Step-by-step explanation:
Given: The tire on franks bike moves in one rotation =75 inches
Since 1 feet = 12 inches
Therefore, 50 inches =[tex]50\times12=600\text{ inches}[/tex]
Now, the number of rotations(r) the tire will have made after frank rides 50 feet is given by :-
[tex]r=\frac{50\text{ feet}}{75\text{ inches}}=\frac{600\text{ inches}}{75\text{ inches}}=8[/tex]
Hence, the tire will have made 8 rotations after frank rides 50 feet.
