Answer:
It would take them 6.5 hours to walk 15 dogs together.
Step-by-step explanation:
John can walk 2 dogs in 1 hour.
If you multiply that by 3, he can walk 6 dogs in 3 hours.
So that means he can walk 8 dogs in 4 hours.
Susie can walk 7 dogs in 2.5 hours.
Meaning that if you add 8 dogs plus 7 dogs, you get 15 dogs.
Meaning that if you add 4 hours plus 2.5 hours, you get 6.5 hours.
That being said, they can both walk 15 dogs TOGETHER in 6.5 hours.
