Question

Greg is running a marathon while running he should drink 22 oz of water per hour if he runs for 4 hours how much water should he drink

Answer 1

22 times 4 would be 88 oz of water she is drinking

Answer 2

Every hour, Greg is drinking 22 oz of water. We should make an equation where x is the amount of hours at any given time while y is the amount of water he should drink.
22x=y
If we are looking for 4 hours, plug 4 in for x.
22(4)
88
Greg should drink 88 oz of water if he is running for 4 hours.
