Agiant tortoise can walk about 1/10 meter per second on land. a cooter turtle can walk about 1/2 meter per second on land. how long would it take a giant tortoise to travel 5 meters? how much longer would it take a giant tortoise than a cooter turtle to travel 10 meters on land?

The rate of giant tortoise is 1/10 meters per each second.
The rate of cooter turtle is 1/2 meters per each second.

How long would it take a giant tortoise to travel 5 meters?
1 second : 1/10 m = X : 5 m
1/10x = 5
x = 50 seconds

How much longer would it take a giant tortoise than a cooter turtle to travel 10 meters on land?
1 second : 1/2 m = X : 10 m
1/2x = 10
x = 20 seconds

So the giant turtle can travel 5 meters in 50 seconds.
So the cooter turtle can travel 10 meters in 20 seconds.
