Sam, Rob and Jim all leave the "START" location at the same time. Sam follows Route A, Rob follows Route B, and Jim follows Route C so they each arrive at the same "END" location. Each grid square represents 100 m distance. a) Which route is the shortest? b) What is the difference in the distance that Sam travelled compared to Jim? c) If Jim is travelling at an average speed of 16 m/s from Start to End, what average speed must Sam and Rob travel to arrive at the exact same time as Jim? Give your answer in m/s. NOTE: For this problem you need to know that the formula for the distance around the outside of a circle (called the "circumference") is C = 2nr, where r is the radius of the circle. Assume the radius of Town Hall is 200 meters.

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
