90 meters

20 minutes - 30 meters
60 minutes - ? meters

There are two ways to solve this.

--

The first (slightly longer) way is to find how many meters the slug travels per minute.

$30 \div 20 = 1.5$ $30 -: 20 = 1.5$ meters per min

so in 60 minutes it would travel

$60 \times 1.5 = 90$ $60 xx 1.5 = 90$ meters

--

The second method requires you to realise that 60 is three times 20.

That means you just have to multiply the distance traveled in 20 minutes by 3 to get the distance traveled in 60 minutes.

$30 \times 3 = 90$ $30 xx 3 = 90$
