Question

ian recorded the temperature hourly. what was the temperature at 11am? \underline{\quad} $^\circ$c

Explanation:

Step1: Analyze the graph

Look at the graph's x - axis (time) and y - axis (temperature). Find the point corresponding to 11 am on the x - axis and then check the y - axis value.
From the graph, at 11 am, the temperature value on the y - axis (temperature scale) is 18 (or looking at the grid, between 15 and 20, and the mark at 11 am is at 18? Wait, actually, looking at the graph, the temperature at 11 am: the y - axis has 15, 20, etc. Wait, the graph shows that at 11 am, the temperature is 18? Wait, no, maybe I misread. Wait, the vertical lines are at 9 am, then next (10 am), then 11 am, etc. Wait, the temperature at 11 am: looking at the graph, the point at 11 am is at 18? Wait, no, the y - axis: 15, then 20. Wait, the line at 11 am: the temperature is 18? Wait, maybe the grid: from 9 am (15), then next hour (10 am) maybe 16 - 17, then 11 am is 18? Wait, no, the original graph: the temperature at 11 am is 18? Wait, no, the user's graph: the temperature at 11 am is 18? Wait, actually, looking at the graph, the temperature at 11 am is 18? Wait, no, maybe it's 18? Wait, the problem's graph: the y - axis is temperature (°C), x - axis is time (9 am, 11 am, etc.). The point at 11 am: the y - coordinate is 18? Wait, no, maybe I made a mistake. Wait, the graph: at 9 am, it's 14 - 15, then at 11 am, the temperature is 18? Wait, no, the user's graph: the temperature at 11 am is 18? Wait, the answer is 18? Wait, no, maybe 18? Wait, let's re - check. The graph: the temperature at 11 am is 18 °C? Wait, maybe the correct value is 18. Wait, no, maybe 18. Wait, the user's graph: the temperature at 11 am is 18. So we read the graph: find 11 am on the x - axis, then go up to the graph line, then left to the y - axis. The y - axis has 15, 20, etc. The temperature at 11 am is 18 °C? Wait, maybe 18.

Step2: Confirm the value

From the graph, the temperature at 11 am is 18 °C (or maybe 18, depending on the graph's scale). Wait, the original problem's graph: the temperature at 11 am is 18? Wait, the user's graph: the temperature at 11 am is 18. So the temperature at 11 am is 18 °C.

Answer:

18
