=+Consider how set-up reduction principles can be used on the following:

(a) Changing a tyre at the side of the road (following a puncture).

(b) Cleaning out an aircraft and preparing it for the next flight between its inbound flight landing and disembarking its passengers, and the same aircraft being ready to take off on its outbound flight.

(c) The time between the end of one surgical procedure in a hospital operating theatre and the start of the next one.

(d) The ‘pit stop’ activities during a Formula One race (how does this compare with (a)

above?).
