traveling 60 mi/h what is the speed in feet per second. How do you find this
60 mile * 5,280 feet = feet per hour
60 seconds * feet per hour = feet per second
where did the number 5280 come from.. and i figured it would be with you numbers 19008000 feet per seconds correct.
do it step by step
60 miles/1 hour
= 60(5280) feet/1 hour
= 316800 feet/60 minute
= 316800 feet/3600 seconds
= 88 feet/second
i am confused is it divid or times
Both * and () are symbols for multiplication.
BTW, a rough estimate to change mph to feet/sec
is to take half of the rate in miles and add it on .
i.e. multiply the mph rate by 1.5
reason: 1 mph = 1.4666 feet/sec
