59 miles /1 hour  x    5280 ft / 1 mile   x     1 hour /60 min    x   1m / 60 sec  =  

 

[ 59 * 5280 ] / [ 60 * 60 ]   =  86.5 ft/ sec  = 87 ft / sec

 

BTW....here's an easier formula to use to convert to ft /sec

 

88 ft /sec = 60 mph

 

So

 

59  x   88 /60  =   86.5 ft/sec

 

cool cool cool
