Trigonometry word problem

56. The planet Mercury completes one rotation on its axis every 59 days. Through what angle (measured in degrees) does it rotate in

a) one day

b) one hour

c) one minute

To solve it, would you take 360 degrees divided by 59, which would give us 6.1 degrees and then further it from there by 24 and then by 60 to get the question?

I'm confused because I would think that the measurements would have to be the same to divide them...or am I on the right track? Thanks in advanced!
