Default Speedo Calibration

If I have 4.10 gears, how can I find out what the actual speed the car is running. This is in a m6 car. I only want to know until I have the money to get the speedo calibrated.

You can do it pretty easy, 4.10 / 3.42 = 1.198

so, about 20% slower. So while you read 100MPH on the speedometer, it would be actually 80MPH according to the police man. I think that's right =)
