Please help with chemistry hw?

I need assistance with my chemistry homework. I am trying to determine the average rate of change of substance B from t = 0 s to t = 222 s in the reaction A → 2B. Here is the data I have collected:

Time (s) | Concentration of A (mol/L)
0 | 0.650
111 | 0.400
122 | 0.150

Could you please help me calculate the average rate of change of B during this time interval? Thank you!

rateA = Δ(A)/Δt = (0.150 M – 0.650 M) / (122 s – 0 s) = –0.004098 M/s

rateB = –2 x –0.004098 M/s = 0.008196 M/s***

multiply by -2 to get reaction rate to become a positive number
