This sand timer contains 595 g of sand.
It takes half an hour for all of the sand to flow through the timer.
Each millilitre of sand weighs 1.6 g.
How many millilitres of sand flow through the timer per minute?

12.4
19.8
31.7
743.8

595g ÷ 30mins = 19.8g per min

19.8g per min ÷ 1.6g each mil

= 12.374mil per min rounded

= 12.4mil per min

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
