You are driving a 3.2 Litre, V6 car whose engine speed is 3500rpm.
If the piston face diameter is 80mm, then what is the average speed of the piston?
3.2 litres, refers to total piston volume
3.2 l / 6 = 533,333 mm^3
Base of cylinder = pi * (40 mm) ^2 = 5026.548245743664 mm ^ 2
Vol / base = distance per half cycle = 106.103295394597 mm
This is travelled 7000 times in a minute at 3500 rpm, so the speed is
106.103295394597 * 7000 mm/min = 742723.0677621791 mm/min.
That's 44.56338406573074 km/hr or 27.69040308705332 mi/hr.
To make the precision consistent with the input, make that 45 km/hr or 28 mi/hr.

Another way of saying it.
