Answer:
74.94 miles per hour
Step-by-step explanation:
We simply need to convert "inches per second" to "miles per hour"
We would need to know few of these:
1 mile = 5280 feet
1 feet = 12 inches
and
60 seconds = 1 minute
60 minutes = 1 hour
We setup few proportions and cancel units and multiply/divide the numbers to arrive at our answer (shown below):
[tex]\frac{1319Inches}{Second}*\frac{1Feet}{12Inches}*\frac{1Mile}{5280Feet}*\frac{60Second}{1Minute}*\frac{60Minute}{1Hour}\\=\frac{1319*60*60}{12*5280}\\=\frac{4748400}{63360}\\=74.94[/tex]
So , rounded to 2 decimal places, it is 74.94 miles per hour
