Explanation:
Given that,
Distance covered by the snail, d = 300 cm
Time taken, t = 1 hour
(a) Speed of the snail is given by :


v = 300 cm/h
(b) Since, 1 hour = 60 minutes
Speed of the snail is given by :


v = 5 cm/min
(c) Since, 1 meter = 100 cm
Distance, d = 3 meter
Speed of the snail is given by :

v = 3 m/h
Hence, this is the required solution.
