About 671,000,000 miles per hour! However, even at that rate, it takes 2.5 million years to reach the nearest galaxy, Andromeda.

186,000 mi/sec x 60 sec/min x 60 min/hr = 186,000 x 3,600 mi/hr = 669,600,000 miles per hour. The attached link says 671,000,000 mph but doesn't show the calculation.

A more accurate value for 'c' is 186,282 mps. The calc'd value is then 186,282 x 3,600 = 670,615,200 mph.
