Given Information:
The temperature at noon in Madras varies according to the function -t^2/2 + 8t + 3, where t is the elapsed time.
Calculating Temperature Difference:
To find the temperature difference between 4 pm and 9 pm, we need to calculate the temperature at 4 pm and 9 pm separately using the given function and then find the difference.
- At 4 pm (t = 4):
Temperature = -(4^2)/2 + 8(4) + 3 = -8 + 32 + 3 = 27
- At 9 pm (t = 9):
Temperature = -(9^2)/2 + 8(9) + 3 = -40.5 + 72 + 3 = 34.5
Calculating the Difference:
Temperature difference = Temperature at 9 pm - Temperature at 4 pm
= 34.5 - 27
= 7.5
Therefore, the temperature difference between 4 pm and 9 pm is 7.5. Hence, the correct answer is option 'B) At 9 pm 7.5 more'.

Calculating the Difference:
Temperature difference = Temperature at 9 pm - Temperature at 4 pm
= 34.5 - 27
= 7.5
Therefore, the temperature difference between 4 pm and 9 pm is 7.5. Hence, the correct answer is option 'B) At 9 pm 7.5 more'.
