00:00:01.450 --> 00:00:04.300
The table shows the temperatures in some cities in a day.
00:00:04.830 --> 00:00:08.300
Find the city that has the closest temperature to that of city A.
00:00:09.950 --> 00:00:12.970
And then we’ve got a range of different cities with different temperatures.
00:00:13.000 --> 00:00:24.020
So A is twenty-seven degrees Celsius, B is twenty-five degrees Celsius, C is thirty-eight degrees Celsius, D is thirty-two degrees Celsius, and E is twenty-three degrees Celsius.
00:00:25.740 --> 00:00:30.980
Right, let’s picture our thermometer and I’m just gonna map the temperatures onto that thermometer.
00:00:31.910 --> 00:00:44.820
So A is twenty-seven degrees Celsius, B is twenty-five, C is thirty-eight, D is thirty-two, and E is twenty-three.
00:00:46.540 --> 00:00:52.330
Now the question asked us to find the city that has the closest temperature to that of city A.
00:00:55.410 --> 00:00:59.940
Now I’d have to step up five degrees Celsius to get up to D.
00:01:00.980 --> 00:01:05.930
But I’d only have to step down two degrees Celsius to get down to B.
00:01:07.180 --> 00:01:16.410
So the difference in temperature between cities A and D is five degrees Celsius and the difference in temperature between cities A and B is only two degrees Celsius.
00:01:16.580 --> 00:01:19.690
So city B has got the closest temperature to city A.
00:01:21.180 --> 00:01:27.340
Now you didn’t have to draw out the scale; you could have just done the calculations by hand and done a bit of subtraction or addition.
00:01:27.780 --> 00:01:32.420
But our answer either way is city B has the closest temperature to city A.
