Final answer:
The kangaroo takes 6 minutes to travel 2 kilometers.
Step-by-step explanation:
To find out how long it takes for the kangaroo to travel 2 kilometers, we can set up a proportion using the given information. We know that the kangaroo hops 2 kilometers in 3 minutes, so the proportion is: 2 km / 3 min = 2 km / x min. To solve for x, we can cross multiply and get: 2 km * x min = 2 km * 3 min. Simplifying this equation, we have: x min = 6 min.
Therefore, the kangaroo takes 6 minutes to travel 2 kilometers.
