Final answer:
Joanna drinks approximately 2.36588 liters of water per day as per her coach's recommendation, calculated by converting the total number of ounces (80) to liters using the conversion factor.
Step-by-step explanation:
Converting Ounces to Liters
Joanna's coach has recommended that she drink ten 8oz glasses of water each day during her training. To calculate how much water she is drinking in liters, we must use a conversion factor. Since 1 ounce is equivalent to 0.0295735 liters, we can multiply the number of ounces she drinks by this conversion factor. Joanna drinks 10 glasses x 8 ounces per glass, which equals 80 ounces of water per day. To find out how many liters this is, we multiply 80 ounces by 0.0295735 liters per ounce.
80 ounces x 0.0295735 liters/ounce = 2.36588 liters.
Therefore, Joanna is drinking approximately 2.36588 liters of water per day during her training.
