Trains travel from one town to another town all day, always on the same track, always going nonstop and at the same speed. The noon train took 80 minutes to complete the trip, but the 4 PM train took an hour and 20 minutes. Why?
I flop around on sticks and sometimes you cheer me as I do, I desperately need a white powder to do what needs to be done, and looking at me you might wonder why I look like I am about to go swimming. What am I?
Only one color, but not one size, Stuck at the bottom, yet easily flies. Present in sun, but not in rain, Doing no harm, and feeling no pain. What is it?
Susan uses a toaster that has 2 slots. The toaster toasts one side of each piece of bread at a time, and it takes exactly 1 minute to do so.
If Susan wants to make three pieces of toast, what is the LEAST amount of time she needs to toast them on both sides?
3 minutes.
She puts two pieces in the toaster, toasting one side of each. Then she flips one of them, takes one out, and puts the completely untoasted piece into the toaster. Finally, she takes out the toasted piece and puts the two half-toasted pieces of bread into the toaster for a minute and she's done.
