The table shows the temperatures of four cities at 11 a.m. and the changes in these temperatures in the next three hours. Which city is the coldest at 2 p.m.?

Question

Temperature at 11 a.m. (°C) Change (°C) at 2 p.m.
City P - 9 8 degrees warmer
City Q 7 7 degrees colder
City R - 3 3 degrees warmer
City S 4 6 degrees colder

A. City P

B. City 2

C. City R

D. City S

Answer 1

To find the temperature at 2 p.m., we need to add the change in temperature to the temperature at 11 a.m.

For City P: -9 + 8 = -1
For City Q: 7 - 7 = 0
For City R: -3 + 3 = 0
For City S: 4 - 6 = -2

The coldest city at 2 p.m. is City S with a temperature of -2°C. Therefore, the correct answer is D. City S.
