I assume you mean deceleration, or else it is speeding up.
Also, acceleration is measured in rad/s^2.
1200 rpm is 2400π/60 rad/s = 40 rad/s
so, if it loses 4 rad/s every second, how long will it take to lose all 40 rad/s?

NO!
40rad/s
---------------- = 10s
4 rad/s^2
how could you possibly have come up with 40?
