Question
The graph above shows the temperature in a room during a day when the thermostat malfunctioned. For which of the following two-hour periods was difference between the maximum and minimum temperatures greatest?
- 1:00 to 3:00
- 3:00 to 5:00
- 5:00 to 7:00
- 7:00 to 9:00
The correct answer is: 3:00 to 5:00
HINT :- Find estimated minimum and maximum temperature in all the given time period of options and find the difference between them .now mark the time period with greatest difference .
A. At 1 - 3 maximum temperature = 55(℉) and minimum temperature = 50(℉)
Difference is 55 - 50 = 5(℉).
B. At 3 - 5 maximum temperature = 70(℉) and minimum temperature = 53(℉)
Difference is 70 - 53 = 17(℉).
C. At 5 - 7 maximum temperature = 84(℉) and minimum temperature = 70(℉)
Difference is 84 - 70 = 14(℉).
D. At 1 - 3 maximum temperature = 85(℉) and minimum temperature = 79(℉)
Difference is 85 - 79 = 6(℉).
The maximum difference is 17(℉) in between 3.00 to 5.00.
