What is the rotational speed of the Second Hand on a clock.

Question

Note, the answer must be in rev/s.
The Hour Hand is 2.31e-05 rev/s;
The Minute Hand is 2.78e-4 rev/s. I've checked with 3 tutors and none of them have gotten an answer that is considered correct. I'm completely stumped.
Thank you

Answer 1

it takes 60 s for one revolution

so it must be 1/60 r/s

Answer 2

it appears to be a format problem

1/60 = 1.67E-2 rev/s

Answer 3

Thank you, Scott

Answer 4

W=2pi/T but here T=60 W=2*3.14/60=6.28/60= 0.10rev/s ans
