Question

On January 1st, the temperature in St Petersburg was -7°C and the temperature in Rome was 15°C. The temperature in Reigate was exactly halfway between St Petersburg and Rome. What was the temperature in Reigate?​

Answer 1

4°C

Explanation:

Try drawing it on a number line and counting 11 from -7° C and 11 from 15°C you'll end up with 4°C as the middle

Answer 2

To find the temperature in Reigate, which is halfway between St. Petersburg and Rome, we need to find the average of the two temperatures.

Average = (Temperature1 + Temperature2) / 2

Average = (-7 + 15) / 2 = 8 / 2 = 4

So, the temperature in Reigate was 4°C.
