Question

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

(i) What was the patient’s temperature at 1 p.m.?
(ii) When was the patient’s temperature ${38.5}^{\circ }$ C?
(iii) The patient’s temperature was the same two times during the period given. What were these two times?
(iv) What was the temperature at 1.30p.m.? How did you arrive at your answer?

Answer 1

(i) The patient’s temperature was ${36.5}^{\circ }C$ at 1 p.m.
(ii) The patient’s temperature was ${38.5}^{\circ }$ C at 12 noon.
(iii) The patient’s temperature was same at 1 p.m. and 2 p.m.
(iv) The temperatureat 1.30 p.m.is ${36.5}^{\circ }C$.
The point between 1 p.m.and 2 p.m., x is is equidistant from the two points showing 1 p.m.and 2 p.m. So it represents 1.30 p.m. Similarly the point on y axis, between ${36}^{\circ }Cand{37}^{\circ }C$ will represent ${36.5}^{\circ }C$
