The drawing shows two thermometers, A and B, whose temperatures are measured in °A and °B. The ice and boiling points of water are also indicated.
(a) Using the data in the drawing, determine the number of B degrees on the B scale that correspond to 1 A° on the A scale.
(b) If the temperature of a substance reads +40.0°A on the A scale, what would that temperature read on the B scale? (Cutnell 354)
