Answer:she walks about 6 dogs each day.
Explanation:
Marie walks her neighbors dogs for an hour and 40 minutes each day after school. Converting an hour and 40 minutes to minutes, it becomes
1 × 60 + 40 = 60 + 40 = 100 minutes.
If it takes Marie 17 minutes to walk a dog around her neighborhood, then the number of dogs that she walks each day would be
100/17 = 5.88 dogs
Since the number of dogs must be whole number, then the number of dogs is 6
