To measure the speed of a current, scientists place a paddle wheel in the stream and observe the rate at which it rotates. If the paddle wheel has radius 0.40 m and rotates at 100 rpm, find the speed of the current in m/s.

 I got a answer (4.190......) but it marked me wrong, I have just one more chance, I would highly appreciate your help !!

1.25 etc * 100=125.66 etc
125.66m per minute divided by 60=2.09 etc m per second
