Glimpse into a Girl's Mind

Abigail's math book: "A grain auger is driven by an electric motor with a 3-inch pulley turning at 1,750 rpm. The belt around this pulley drives a 13-inch pulley with a 3 1/2 inch sprocket on the same shaft; both pulley and sprocket turn at the same speed. The 3 1/2 inch sprocket turns a chain that drives the 12-inch sprocket of the auger. What is the speed of the 12-inch sprocket?"

Abigail's answer: "1,750 rpms? Sprocket? Auger? Rpm's? Shafts? Pulley? WHAT?? This problem is for Mennonite farmers who lived 200 years ago - not me!"

Know exactly how you feel Abi. I'm going through the same thing in Chemistry .. Hang in there, it'll be done in another 4 or 5 years :)
