#### Answer

Snowmobile/ATV and Person walking

#### Work Step by Step

The thickness of the ice is given as (1 )/2 ft.
To find what the ice lake will support in (1 )/2 ft thick ice layer, we need to convert feet into inches because in the bar graph the data is given in inches.
1/2 ft = --- inches
You are converting from a larger unit to a smaller unit (a foot is longer than an inch), so multiply.
Because 1 ft = 12 in., multiply by 12.
1/2 ft = 1/2 * 12/1 = 6 inches
Since the thickness is 6 inches it will support Snowmobile/ATV and Person walking because the provided thickness is 5 in. and 4 in. which is less than 6 in.
