1 hour = 60 minutes, 1 minute = 60 seconds so 1 hour = 60*60 seconds.
1 hour/40 secs = 3600 sec/40 sec = 90 of them.
Use the units to help figure this out. There are 5280 feet per mile = 5280 ft / 1 mile There are 3600 seconds in an hour = 3600 sec / 1 hour 80 Miles / 1 hour = 422400 ft / 1 hour = 422400 ft / 3600 Sec = 117.3333 ft / sec
48 (hours) x 3600 (seconds in 1 hour) = 172,800 seconds
60sec = 1 min 60min= 1 hr so, 60sec x 60min = 3600 seconds in 1 hour 3600sec x 1/8, (or 3600sec / 8) =450 sec
1 hour = 60 minutes, 1 minute = 60 seconds so 1 hour = 60*60 seconds.
1 hour/40 secs = 3600 sec/40 sec = 90 of them.
100 sec = 0.02777... hour (rounded) 1 hour = 3,600 seconds
1 hour = 3600 seconds.
1 hour = 3,600 seconds
1 hour = 60 x 60 = 3600 sec 48 hours = 48 x 3600 = 172800 sec
180 ft/1 sec x 1 mile/5280 ft x 3600 sec/1 hour = 122.73 miles/hour
45 sec / 1 hr = 45 sec / 3600 sec = 1/80
1 hour = 60 min 1 min = 60 sec 60•60=3600 sec = 1hour
60 sec = 1 minute 60 min = 1 hour 3600 sec = 1 hour one mile/sec = 3600 mph - pretty fast!
(111.95 ft / 1 sec) * (1 mi / 5280 ft) * (3600 sec / 1 hour) =~ 76.34 miles per hour.
