Question

The following graph shows the temperature of a patient in a hospital, recorded every hour.

What was the temperature at 1.30 p.m.?

• A. ${34.5}^{0}C$
• B. ${37.5}^{0}C$
• C. ${36.5}^{0}C$
• D. ${33.5}^{0}C$

Answer 1

The correct option is C ${36.5}^{0}C$

The temperature at 1:30 PM will be ${36.5}^{o}C$; The point between 1 p.m. and 2 p.m. on the x-axis is equidistant from the two points showing 1 p.m. and 2 p.m., so it will represent 1.30 p.m. Similarly, the point on the y-axis, between ${36}^{o}C$ and ${37}^{o}C$ will represent ${36.5}^{o}C.$
