Help me with this problem.I'm frustrated because i'm not getting the right answer.Worked it out thrice already?
Ethylene glycol is the main component in automobile antifreeze. To monitor the temperature of an auto cooling system, you intend to use a meter that reads from 0 to 100. You devise a new temperature scale based on the approximate melting and boiling points of a typical antifreeze solution (-45°C and 115°C). You wish these points to correspond to 0° and 100°A, respectively. Your thermometer reads 89°A. What is the temperature in °C and in °F? What is the temperature of 55°C in °A?
so, your antifreeze scale is 0 100
which for celsius is -45 115
so your 89 measure is here 89
To find in Celsius say that 89 deg is 89/100 up the scale
so in Celsius it is ((89/100) * (115+45)) + -45 = 97.4 degrees Celsius
For 55 deg C say that is is (55+45)/(45+115) = 0.625
62.5/100 on the deg A scale is 62.5 deg
