Mastering Physics?

Does anybody think they could help me with a masterphysics question?

Really hard Physics Problem:

It should be noted that the same equations apply to events in your everyday life. The reason that you don't notice them is that objects in your everyday life move so much slower than the speed of light. Now let's look at the differences in measurements between two frames moving relative to one another at a speed of 30 (108 or about 67 ). Your calculator may not be able to store enough digits to work these problems accurately, so you may need to use the approximations from the binomial expansion:

1/sqroot 1- (u^2/c^2) = 1 + 1/2(u^2/c^2)
AND
sqroot(1-(u^2)/c^2 = 1-(1/2)(u^2/c^2)

What would be the difference between the time measured by an observer moving at 30 and the proper time for a proper time interval of 1 hour (3600 )? The answer is small but nonzero. You will need to find an expression for the time difference using the approximation given in this problem before you substitute in the numbers; otherwise your calculator will just give zero.
Express your answer in seconds to three significant figures. Use c = 3 * 10^8 m/s
