Answer:
Rate of movement of snail, s = 0.25 meters per hour
Explanation:
It is given that,
Distance covered by snail, d = 0.5 m
The snail moved this distance in 2 hours
Since, 1 hour = 3600 seconds
So, 2 hour = 7200 seconds
We have to find the rate of movement of snail i.e. s
[tex]s=\dfrac{d}{t}[/tex]
So,
[tex]s=\dfrac{0.5}{7200}[/tex]
s = 0.000069 m/s
Converting m/s to m/h
So, s = 0.248 m/h
or s = 0.25 meters per hour
Hence, the correct option is (d)
