CC - MATHS AND WATER
A scientist has 3 glasses
He wants to make warm water as quickly as possible.What should he do?
2. System of linear equations:
A chef needs exactly 5 liters of warm water at a temperature of 40ºC to activate yeast for a baking recipe. She only has access to cold tap water at 15ºC and boiling water from a kettle at 90ºC. Assuming no heat is lost to the surroundings, how many liters of cold water and how many liters of boiling water must she mix together to get the desired volume and temperature?"
