How do I solve this problem on the reaction 2A+B==> C+ 2D

Consider the reaction 2A+B==> C+2D. The rate law for this reaction is first order in A and second order in B. If the rate constant at 25°C is 3.01×10^2 s^-1  find the rate of reaction when the concentration of A is 0.47M and the concentration of B is 0.79M.

First write the rate law:
Rate = k [A][B]2   *remember that the exponents refer to the order with respect to each reactant
Then all you have to do is plug in values:
Rate = (3.02*102)[0.47][0.79]2
Solve for Rate (M/s)
