We know that,

The average rate of reaction = \frac{-\Delta [R]}{\Delta t}

                                              = -\frac{ [R]_{2}-[R]_{1}}{t_{2}-t_{1}}

                                              = \frac{0.03-0.02}{25}Mmin^{-1}

                                              = 4\times 10^{-4}Mmin^{-1}

In seconds we need to divide it by 60. So,

                                              = \frac{4\times 10^{-4}}{60}Msec^{-1}

                                              = 6.67 \times 10^{-6}Msec^{-1}
