60 miles/hour * 5280 feet/mile * hour/60 minutes * minute/60 secound = 88 feet/second

In HO, 3.5mm = 1 foot.

88 * 3.5 = 308mm (12 1/8").

So in HO scale, a train traveling 308mm (approximately 1 foot) per second is going 60 scale mph.

speed, time and distance have a linear relationship; thus 2 seconds for 308mm is 30 scale mph.
