Answer

To calculate the total rainfall over the three days, we sum the rainfall amounts for each day.

  • For Monday: 0.0 mm
  • For Tuesday: 3.9 mm
  • For Wednesday: 0.5 mm

Total Rainfall = 0.0 + 3.9 + 0.5 = 4.4 mm.

Answer

To find the temperature range for Monday, we subtract the minimum temperature from the maximum temperature.

  • Maximum Temperature: 5 °C
