A group of meteorologists recorded the temperature in some cities at noon on one day.They recorded the temperature in Liverpool using a thermometer that measures to the nearest 0.1 degrees C and found that the temperature was 17.4 degrees C.The temperature in Budapest was 16 degrees C colder than in Liverpool,to the nearest degree.The temperature in Madrid was 24 degrees C warmer than the temperature in Budapest,to the nearest degree.Work out the lower and upper bounds of the temperature at noon in Madrid.Give your answer in degrees C.

Final answer:

The lower and upper bounds of the temperature at noon in Madrid are 24.36 C and 26.44 C, after considering the precise recording in Liverpool and the rounded differences in temperatures when compared to Budapest and Madrid.

Step-by-step explanation:

To find the lower and upper bounds for the temperature in Madrid, we start by determining the temperature in Budapest, which is “16 degrees C colder than Liverpool”, and then calculate the bounds for Madrid which is “24 degrees C warmer than the temperature in Budapest”.

The temperature in Liverpool is 17.4 degrees C, measured to the nearest 0.1 degrees C, so its lower bound is 17.35 C and its upper bound is 17.45 C. The temperature in Budapest, measured to the nearest degree, is 16 degrees C cooler. The largest the difference could be while still rounding to 16 C is 16.49 C cooler, and the smallest difference could be 15.5 C cooler. This gives us bounds for Budapest's temperature:

  • Upper Bound: 17.45 - 15.5 = 1.95 C
  • Lower Bound: 17.35 - 16.49 = 0.86 C

For Madrid, which is 24 degrees C warmer than Budapest to the nearest degree, we'd have a maximum possible difference of 24.49 C and a minimum of 23.5 C.

  • Madrid Upper Bound: 1.95 + 24.49 = 26.44 C
  • Madrid Lower Bound: 0.86 + 23.5 = 24.36 C

The lower and upper bounds of the temperature at noon in Madrid are 24.36 C and 26.44 C respectively.
