To identify: The correct option a bicycle with 26-in-diameter wheels is travelling at 10mph. To the nearest whole number, how many revolutions does each wheel make per minute
Option (B) is correct option. 129 revolution per minute are required by the bicycle
Given information:
The bicycle with 26-in-diameter wheels is travelling at 10mph. The options are:
Options (A)
Options (B)
Options (C)
Options (D)
Options (E)
Explanation:
Consider the given information
Observe that radius of the bicycle wheel is
Consider the number of revolutions per minutes to be
Then convert revolution per minutes to miles per hour by a series of unit conversion factors
Simplify to obtain
Hence 129 revolution per minute are required by the bicycle
So the correct option is (B).
