The Singapore Flyer is a very tall Ferris wheel.It is 315 meters tall and has a diameter of 150 meters. Each revolution takes about 30 minutes. If you were allowed to ride for 3 hours, how far would you travel? How much of a mile or how many miles would you travel?

A period of revolution of 30 minutes would mean that a 3 hour ride would be how many revolutions?

Total distance traveled by a rider would be that number of circumferences ... $n\pi d$, where $n$ is the number of revolutions and $d$ is the wheel's diameter.

Since diameter is given in meters, calculate the total distance in meters, then convert to miles. One can do that on Google by typing in meters to miles in the search box.
