Conversion Factor
how fast is 55mi/hr in ft/sec?
(55mi/hr) (5280ft/1mi)(1hr/3600sec)= you'll get the answer
A nice conversion factor to MEMORIZE is that 60mph=88fps
so, 55/60 =X/88
and you have it.
To find out how fast 55 miles per hour is in feet per second, we need to use a conversion factor. A conversion factor is a ratio that relates two different units of measurement.
In this case, we want to convert from miles per hour (mi/hr) to feet per second (ft/sec).
The first step is to establish the conversion factor between miles and feet.
1 mile is equal to 5280 feet.
Next, we need to consider the time aspect. Since we want to convert from hours to seconds, we need to know how many seconds are in one hour.
1 hour is equal to 60 minutes, and 1 minute is equal to 60 seconds. So, there are 60 x 60 = 3600 seconds in one hour.
Now, we can set up our conversion factor:
55 miles/hour * (5280 feet/1 mile) * (1 hour/3600 seconds)
By multiplying these conversion factors together and canceling out the units, we can find the answer:
55 miles/hour * (5280 feet/1 mile) * (1 hour/3600 seconds) = 88 feet/second
Therefore, 55 miles per hour is equal to 88 feet per second.
