First, work out how many seconds are in an hour (there are 60 seconds in a minute and 60 minutes in an hour - 60 x 60). 130 x 3600 (or 60 x 60) tells you how many meters in an hour. Now convert the meters to miles. There are 1609 meters in a mile. Divide the m/h by 1609: 468,000/1609. This equals 290.9mph.
