The table shows the temperature of four cities at 11!:00am and the changes in these temps in next 3 hours which city is coldest at 2pm
-9. 8 degrees warmer
7 7 degrees colder
-3. 3 degrees warmer
4. 6 degrees colder
To determine which city is the coldest at 2pm, we need to calculate the temperatures of each city at that time.
City 1:
Temperature at 11am = -9
Change in temperature in the next 3 hours = 8 degrees warmer
Temperature at 2pm = -9 + 8 = -1
City 2:
Temperature at 11am = 7
Change in temperature in the next 3 hours = 7 degrees colder
Temperature at 2pm = 7 - 7 = 0
City 3:
Temperature at 11am = -3
Change in temperature in the next 3 hours = 3 degrees warmer
Temperature at 2pm = -3 + 3 = 0
City 4:
Temperature at 11am = 4
Change in temperature in the next 3 hours = 6 degrees colder
Temperature at 2pm = 4 - 6 = -2
Comparing the temperatures at 2pm, we find that City 4 has the coldest temperature. Therefore, City 4 is the coldest at 2pm.
