Question

Joseph has a job walking dogs and gets paid per dog. He needs to walk 45 dogs to earn enough money to pay for his soccer team fees. If each walk takes the same amount of time, and he can walk 3 dogs in 1 hour and 30 minutes, how long will it take him to walk 45 dogs?

hours

Answer 1

22 hours and 30 minutes

Explanation:

I converted the time for 3 dogs into minutes. Then divided the 90 minutes by 3. Which meant one dog takes 30 minutes per walk. With that I multiplied 30 minutes by 45 (dogs) which gave me to total 1350. Which is in minutes so I converted that to hours by dividing it by 60. Which gave me 22.5 or 22 and a half hours
