Seth traveled one mile in 57.1 seconds. about how fast does seth travel in miles per hour?

Since we need to convert “miles per second” to “miles per hour,”  we first need to find out how many seconds there are in a hour.
We know that there are 60 seconds in a minute, and if we wanted to do an hour we would have to do 60 * 60 which is 3600 seconds, therefore, 
1 mi/57.1 sec = (1 mi/ 57.1 sec)(3600 sec/1 hour)

                        = (3600/57.1) mi/hours

                        = 63.047 mi/hours
