“The formula is quite easy”, the learned policeman smiled. “The speed you can go beyond the limit before being done may be expressed as (S1S) > ((S/((100E)/100)+/ (100x(1d1/d2))/100))+A)S where S1 is your forward velocity as indicated on the car’s speedometer. S is the speed limit as displayed on the warning signs. E represents the standard percentage error in your speedometer with a plus or minus factor of the additional percentage error if the tyres are not standard, with d1 being the original tyre diameter and d2 the diameter of nonstandard tyres filled postmanufacture. A is a completely arbitrary additional speed in mph decided by the local constabulary and can vary from 0 to 9mph and , quite frankly, makes the rest of the calculation pointless.”
“Of course if its chuckingout time at the primary school the formula is much simpler and you’ll get done if S1 >S. The same simplified formula will also apply if you are black.”
Getting into his stride the emeritus young constable added. “Other variations are equally simple. You may escape prosecution if S1 > S2 where S2 is the maximum velocity of the chasing police vehicle or if M1 = M2, where M1 is your lodge and M2 is that of the Chief Constable.

OK OK Lord knows how I did this twice. I got carried away with the algebra, didn't want to lose it, then noticed an error, tried to correct it and ...bollocks.
