Answer:
94.28 inches/second.
Step-by-step explanation:
The length of the circumference of the circular path with 10 inches radius is = inches.
Now, the point on the edge of the wheel moves by 3 revolutions in 2 seconds.
So, in 2 seconds the point moves a linear distance of (3 × 62.85) = 188.57 inches.
Therefore, the linear velocity of the point in inches per second is inches per second.
