Lisa was told that a portion of the restaurant on the Space Needle in Seattle rotates at a rate of 8 radians
per hour. When asked to find the distance through which she would travel if she sat at a table 20 feet
from the center of rotation for a meal lasting 2 hours, she produced the following result:
0=s/r
8=s/20
160=s
The distance is 160 feet.
Lisa did the calculation correctly in finding the he distance per hour, but because the meal lasted () hours, the total distance is the rate times the time or () feet.
