✔ 最佳答案
Answer: 4 meter per hour.(4mph)

80 meter per 20 hours = 80m/20h

Why? Because to find speed, the equation is:
Speed = Distance ÷Time

So,
80 (the distance) ÷20 (the time)= 4 (speed)

Answer is 4 meter per hour (4mph).

Well, since you are trying to find out the speed in meters PER hour, you are trying to find the unit rate, in which how far does the snail travel in 1 hour.
Since it is Meters PER Hour, it is 80 divided by 20.
80/20 is 4. So the snail travels in 4 meters per hour.

you are looking for metres per hour
m/h

given: 80 metre/ 20 hours
80/20 metres/20/20 hours
4 metres/hour

80/20 gives you the average rate per hour
2008-02-19 2:38 am
4 meters per hour 80/20

divide 80 by 20 = 4 m per hour x 24 = 96 m per day
