Nick recorded the distance each cricket jumped. Distance for cricket A: 1 3/4 feet and Distance B: 3 2/4 feet Nick claims that cricket B jumped 2 1/4 feet farther than cricket A because the difference between the whole numbers is 2 and the difference between the numerator is 1.
Explain why Nick's reasoning is incorrect.
What is the correct difference, in feet, between the distance cricket A jumped and the distance cricket B jumped.

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?
