108

Explanation:

1/3 hour = 18 potatoes

therefore,

1 hour = 18 * 3 = 54 potatoes

2 hours = 54 * 2 = 108 potatoes

we also can use the followings:

let say x potatoes can be peeled within 2 hour

x = 2 ->i,
and
18 = 1/3 ->ii

divide i and ii accordingly (number with number and hour with hour)
x/18 = 2/(1/3)

x = 2/(1/3) * 18

x = 6 * 18 = 108
