If a wheel has a circumference of 78 inches, what is the distance covered in 5 rotations of the wheel?

To determine the distance covered in five rotations of a wheel with a circumference of 78 inches, you multiply the circumference of the wheel by the number of rotations.

In this case, the calculation would be:

Distance = Circumference × Number of Rotations

Distance = 78 inches × 5 rotations

Distance = 390 inches

Therefore, the correct answer is based on the formula for distance traveled by a circular object, which involves multiplying the total number of complete rotations by the distance the wheel covers in one full turn (its circumference). Each time the wheel rotates, it covers a distance equal to its circumference, and thus after five rotations, it has covered a total distance of 390 inches.
