(60 miles/hr) x (1609.344 meters/mile) x (1 hour / 3,600 seconds) =(60 x 1609.344 / 3,600) x (mile - meter - hour / hour - mile - second) =26.82 meters/second (rounded)
First, convert the hours to seconds:10 miles/hour x 1 hour/3600 seconds = .002777 miles/secondNext, convert the miles to feet:.002777 miles/second x 5280 feet/mile = 14.67 feet/second
15 miles/hour
(35 mile/hour) x (1,609.344 meters/mile) / (3,600 second/hour) = 15.646 meter/sec (rounded)
(90 mile/hour) x (1.609344 kilometer/mile) x (1 hour/3,600 sec) = 0.04023 km/sec (rounded)40.234 meters per second (rounded)
3600.
(60 miles/hr) x (1609.344 meters/mile) x (1 hour / 3,600 seconds) =(60 x 1609.344 / 3,600) x (mile - meter - hour / hour - mile - second) =26.82 meters/second (rounded)
There are 3600 seconds in an hour. Therefore going at 3600 miles per hour is equivalent to 1 miles per second.
1 Foot per Second = 0.681818181818182 Miles per Hour
There are 102.67 feet per second in 70 miles per hour.
17.6 feet/second*60 seconds/minute*60 minutes/hour=63360 feet per hour there are 5280 feet in a mile 63360 feet/hour*mile/5280 feet=12 miles per hour 90 miles/12 miles per hour=7.5 hours
You must average at least 9.23 miles per hour to achieve that time.
First, convert the hours to seconds:10 miles/hour x 1 hour/3600 seconds = .002777 miles/secondNext, convert the miles to feet:.002777 miles/second x 5280 feet/mile = 14.67 feet/second
15 miles/hour
(35 mile/hour) x (1,609.344 meters/mile) / (3,600 second/hour) = 15.646 meter/sec (rounded)
1 mile per hour is 1 mile every 3600 seconds. I mile per second is 3600 times faster than this hence, 3600 miles per hour.
(53 miles per hour)(5280 feet per mile)/3600 sec/hour) = 78 feet per second, to the justified number of significant digits.
