Temperature on the Celsius scale (C) is related to temperature on the Fahrenheit scale (F) by the formula C = 5/9(F— 32). What is the difference between a certain pair of temperatures on the Celsius scale?

(1) The difference between the temperatures on the Fahrenheit scale is 45°.

(2) The greater of the two temperatures is 30° on the Celsius scale

Sorry for inconvenience formula edited

@Experts would you pls help me with this problem

c=5/9F - (5/9)32 this is a linear equation. Which means that the

difference between the value at celsius scale and fahrenheit scale will follow linear pattern (constant rate of growth). Thus, difference at one point is adequate for one to find out the difference in celsius scale. therefore, A is suff.

B merely gives a value. nothing can be predicted from it. Thus not suff.

Ans: A
