(For some reason they deleted this lol) Finn goes walking. He starts at point A and travels at a speed of 4 km/h for 1.5 hours to point B. He then travels at a speed of 5 km/h to point C. The scale diagram shows his route. How many minutes does it take for Finn to walk from point B to point C?

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?
