Given :
A train travels 110 miles per hour.
To Find :
How fast does the train travel in feet per second.
Solution :
We know, 1 mile = 5280 feet .
1 hour = 3600 s.
So, speed in feet per second is :
[tex]s=\dfrac{110\ miles \times 5280\ \dfrac{feet}{miles} }{1\ hour\times 3600\ \dfrac{s}{hour}}\\\\\\s=\dfrac{110\times 5280}{3600}\ feet/s\\\\s=161.33\ feet/s[/tex]
Hence, this is the required solution.
