It takes about fifteen minutes walk one dog. How many hours does it take to walk 25 dogs separately?

6.25 hours

Step-by-step explanation:

If it takes fifteen minutes to walk one dog, then we simply have to multiply 15 by 25. We have 25 dogs separately!

15 minutes *25 dogs= 375 minutes

However, the question asks for hours. We can simply convert 375 minutes into hours, knowing that 60 minutes = 1 hour.

Let's divide!

It would take 6.25 hours to walk 25 dogs separately.

I hope this helps! Let me know if you have any other questions :)
