A certain car is capable of accelerating at a rate of 10.60m/s^2. How long does it take for this car to go from a speed of 55mi/h to a speed of 60mi/h?

First you are going to have to do some conversions. Personally, I would suggest converting your two velocities, 55 mi/h and 60 mi/h into SI units (m/s). (The other option would be  converting 10.6 m/s^2 to miles per hour per second...ugh.) So, once you have all SI units (the velocities are in m/s), you have a pretty easy formula to work with:

$$a = \frac{ (V_{f}- V_i) }{ t }$$ 
Solve the equation for time and plug in the values (just be sure to convert the velocities to SI units first).
