# How far can a snail crawl if it moves at an average speed of 8.0cm/min for: A) 3 min? B) 3 hour?

Speed is the distance traveled in unit time. Or speed = distance/time which gives distance = speed*time.

The speed of the snail is 8 cm/min.

In 3 minutes, the snail can travel 8*3 = 24 cm

3 hours is equal to 3*60 = 180 minutes. In 180 minutes the snail can travel 180*8 = 1440 cm

**The snail can travel 24 cm in 3 minutes and 1440 cm in 3 hours.**

Distance = velocity x time, so for the first scenario

8cm/min x 3 min = 24 cm traveled.

There are 60 minutes in one hour, so 3 hours x 60 minutes = 180 minutes.

8 cm/min x 180 minutes = 1440 cm traveled

This assumes the snail is crawling in a straight line, of course - if it changes direction then we have to figure out whether to answer the question with *distance*, which is simply an expression of how much ground the snail has covered (like the odometer reading on a car), or *displacement*, which tells us how far the snail is from its starting point, measured in a straight line (regardless of whether the snail's path was straight or not).
