Final answer:
The average temperature in Winnipeg in July is 27 °C, which is determined by adding the 37 °C increase to January's average temperature, the coldest month, which is typically around -10 °C.
Step-by-step explanation:
The average temperature in Winnipeg in July is given to be 37 °C warmer than the coldest month. To determine July's average temperature, we must first identify the coldest month's average temperature. From the question data, it's noted that the coldest month might have an average temperature of around -10 °C (January's average temperature for Winnipeg).
Adding the 37 °C increase to the coldest month's average, the calculation is as follows: -10 °C (average temperature of coldest month) + 37 °C (increase) = 27 °C. Therefore, the average temperature in Winnipeg in July is 27 °C.
