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, decide 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 +47.0 °A on the A scale, what would that temperature read on the B scale?
