Question

estimate the temperature at 4.30pm. 23°c 27°c 25°c 20°c

Explanation:

First, observe the temperature graph. At 4 pm (or around that time), the temperature is 25°C, and at 5 pm it's 18 - 20°C. 4:30 pm is halfway between 4 pm and 5 pm. The temperature at 4 pm is 25°C, at 5 pm is ~18 - 20°C? Wait, no, looking at the graph: at 4 pm (the vertical line before 5 pm), the temperature is 25°C? Wait, no, the graph shows at 3 pm - 4 pm? Wait, the x - axis: 9 am, 11 am, 1 pm, 3 pm, 5 pm. So between 4 pm (which is between 3 pm and 5 pm) and 5 pm. At 4 pm (let's say the time between 3 pm and 5 pm: at 4 pm, the temperature is 25°C? Wait, no, the graph: after 3 pm, the temperature drops. At 4 pm (the point before 5 pm), the temperature is 25°C? Wait, no, the options: 23, 27, 25, 20. Let's see the trend: from 3 pm (28°C maybe), then at 4 pm (the time between 3 pm and 5 pm), the temperature at 4 pm (the vertical line) is 25°C? Wait, no, the graph: at 3 pm, it's 28, then at 4 pm (the next vertical line) is 25, then at 5 pm is 18 - 20? Wait, no, the options: 23, 27, 25, 20. Wait, 4:30 pm is between 4 pm and 5 pm. The temperature at 4 pm is 25°C, at 5 pm is 18 - 20? No, the graph's last point at 5 pm is 18 - 20? Wait, no, the y - axis: 20 at 5 pm? Wait, the graph's end at 5 pm is 18 - 20? Wait, the options: 23, 27, 25, 20. Let's re - examine: the temperature at 4 pm (the time between 3 pm and 5 pm) is 25°C, then at 5 pm is 18 - 20? No, the graph shows that at 4 pm (the vertical line before 5 pm), the temperature is 25°C, and at 5 pm is 18 - 20? Wait, no, the options: 23 is between 25 and 20? Wait, no, maybe I misread. Let's see the graph again: the temperature at 3 pm is ~28, then at 4 pm (the time point) is 25, then at 5 pm is 18 - 20. So 4:30 pm is halfway between 4 pm (25°C) and 5 pm (20°C)? No, that can't be. Wait, no, maybe the temperature at 4 pm is 25°C, and at 5 pm is 20°C? Wait, the graph's last point at 5 pm is 18 - 20? Wait, the options: 23, 27, 25, 20. Let's think about the trend: after 3 pm, the temperature decreases. At 4 pm (the time between 3 pm and 5 pm), the temperature is 25°C, then at 5 pm is 20°C. So 4:30 pm is between 4 pm (25°C) and 5 pm (20°C). The temperature at 4:30 pm should be between 20 and 25. The options are 23, 27, 25, 20. 27 is higher than 25 (so no, since it's decreasing), 25 is at 4 pm, 20 is at 5 pm. So 23 is between 25 and 20. Wait, but maybe I made a mistake. Wait, the graph: at 3 pm, temperature is 28, then at 4 pm (the vertical line) is 25, then at 5 pm is 20. So 4:30 pm is 30 minutes after 4 pm. The temperature at 4 pm is 25, at 5 pm is 20. So the decrease from 25 to 20 in 1 hour. So in 30 minutes, it would decrease by 2.5, so 25 - 2.5 = 22.5, which is close to 23. So the answer is 23°C.

Answer:

23°C (the option with 23°C)
