Answer:
13.3°F
Step-by-step explanation:
The change in today's temperature between the two readings as measured by Miguel is 13.3°F
Miguel's temperature readings :
Average low temperature = -4.2°F
Avetage high temperature = 9.1°F
The change in temperature is the difference between the two temperature readings :
Average high temperature - Average low temperature
(9.1 - (-4.2))°F
(9.1 + 4.2)°F = 13.3°F
Hence, the change in temperature reading = 13.3°F
