95.3333333 feet per second == you can literally type "65 miles per hour in feet per second" into google and it does unit conversions and math for you.
Use dimensional analysis.50 miles/hour * 1 hour/3600 seconds * 5280 feet/mileThe hour and mile units cancel out, leaving 73.3 feet per second.------------------Dimensional analysis is the best answer - it explains the arithmetic. But it's also interesting and useful to know that Google will do the work for you. Just type:50 miles per hour in feet per secondin the search box and read the answer:50 miles per hour = 73.3333333 feet per second(of course all those extra threes are much too precise for the data given).

Miles and hours are measurements of two different things. Miles are a measurement of distance and hours are a measurement of time. If you are referring to the phrase "miles per hour" (MPH), it is not stating that there are miles in an hour but rather is stating how many miles can be traveled within the duration of an hour, thus offering a type of unit of speed. For instance, if someone is driving 40 MPH, they can travel 40 miles in 1 hour. 1 MPH is equal to 0.44704 m/s (meters per second). So, how many miles you can travel in an hour depends on the MPH you are travelling.

Hours is a measurement of time and miles is a measurement of distance. To calculate the miles per hour numerous factors such as the weather, type and condition of the mode of transportation chosen, traffic conditions, imposed legal speed limits and advisories, roadway construction and obstacles, the time of day and perhaps other variables. Only then can a viable estimate be made of the speed required to travel a known distance in a given amount of time.
