On a straight road (taken to be in the + x direction) you drive for an hour at 40 km per hour, then quickly speed up to 110 km per hour and drive for an additional two hours. how far do you go ( delta x)? total distance = km what is your average x component of velocity (v avg, x) v avg, x = km/hr why isn't v avg, x equal to the arithmetic average of your initial and final values of v x, (40 + 110)/2 = 75 km per hour? the velocity isn't constant. the arithmetic mean is not a valid way to calculate the average in this situation. the initial velocity isn't zero.

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
