1) It says he pours an equal amount into the first 7 beakers after pouring 16mL into the 8th so 70/7 = 10mL per beaker for the first 7.
2) If students rotate through 3 activites, each for 8 minutes, 3*8 = 24 minutes total. If it starts at 11:15, 24 minutes after that would be 11:39 (this represents the time they stop). If lunch starts at 12, there will be 21 minutes between the end of gym activities and the beginning of lunch.
Because both properties just switch around, and you get the same answer
