Answer:
80.67 feet/sec
Explanation:
Use conversion factors:
But the figure of 1 minute = 3.600 seconds cannot be correct. The last time I checked, there were 60 seconds in a minute. There are, however, 3600 seconds in an hour, so I'll use that if the question ever comes up again.
(55 miles/hour)*(5,280 feet/mile)*(1 hour/3600 seconds) = seconds)
= 80.67 feet/sec
"3.90M" if approximate
if u didn't understood why i converted volume from millilitres to litre then refer defination of Molarity.
