Question

The graph between two temperature scales $P$ and $Q$ is shown in the figure. Between the upper fixed point and lower fixed point, there are $150$ equal divisions of scale $P$ and $100$ divisions on scale $Q$ . The relationship for conversion between the two scales is given by:

Graph of temperature on scale Q along horizontal axis and scale P along vertical axis, showing a straight line with vertical difference ΔtP = 150° and horizontal difference ΔtQ = 100° up to marked value 180 on P scale.

A
$t_q/150 = (t_p - 180)/100$
B
$t_q/100 = (t_p - 30)/150$
C
$t_p/180 = (t_Q - 40)/100$
D
$t_p/100 = (t_Q - 180)/150$

Accepted Answer

B. $$t_q/100 = (t_p - 30)/150$$

Answer

A. $$t_q/150 = (t_p - 180)/100$$

Answer

C. $$t_p/180 = (t_Q - 40)/100$$

Answer

D. $$t_p/100 = (t_Q - 180)/150$$
