1 revolution is 1 circumference

 

C  =  2·pi·radius  =  2·pi·40 ft  =  80·pi ft  =  253.3274123 ft

                                                =  253.3274123 ft  x  12 in / ft  =  3015.928947 in

 

10 min  =  10 min  x  60 sec / min  =  600 sec

 

4 revolutions / 10 min  =  4 x 3015.928947 in / 600 sec  =  5.0 in/sec
