Roughly 149 MPH. 240(Km/h) / 1.609344 (Km/M) = 149.129086 (M/h) To work this conversion for any kph to mph, just divide by 1.609 (OR even easier, for an estimate, (1): divide by 3, then multiply the result by 2 ... in other words take 2/3 of the kph ... this will be a touch high. Alternately, (2): multiply by 0.6 ... this will be a touch low.) The accurate factor is 0.62, or 1/1.609344 To calculate the other way, MPH to KPH, multiply by 1.609 or estimate by dividing by 2, then multiplying the result by 3.
