To find Ken's temperature prediction for May, we start with his prediction for February, which is –3°C. He predicts that the average temperature will increase by 11°C by May.
We calculate the May temperature as follows:
\[ \text{May temperature} = \text{February temperature} + \text{increase} \] \[ \text{May temperature} = -3°C + 11°C \] \[ \text{May temperature} = 8°C \]
Therefore, Ken’s temperature prediction for May is 8°C.
