It will take the snail 9.6 minutes to travel 24cm.
Step-by-step explanation:

Ratio of distance to time = 10:4
New distance = 24cm
Let,
x be the time period
Ratio of new distance to time = 24:x
Using proportions;
Ratio of distance to time :: Ratio of new distance to time

Product of mean = Product of extreme

Dividing both sides by 10

It will take the snail 9.6 minutes to travel 24cm.
