How Many Revolutions Does a Slowing Ceiling Fan Make?

[cbrown7]

A ceiling fan is rotating 1.0 rev/s. when turned off, it slows uniformly to a stop in 2.4 min.
How many revolutions does the fan make in this time?
Using the result from the above question, find the number of revolutions the fan must make for its speed to decrease from 1.0 rev/s to 0.50 rev/s.

Help!
thx
