On some days Melvin commutes 3.5 hours per day to the city for meetings. Last week he commuted for a total of 14 hours. How many days did he commute to the city?

4 days

Step-by-step explanation:

In this question, we are asked to calculate the number of days Melvin commutes if she commutes at a certain rate per day and last week, she took 14hours to commute.

Now, this is a rate question. She commutes at a rate of 3.5hrs per day and she commuted a total of 14 hours.

To get the number of days for which she has commuted, we simply divide the number of hours of commuting by the rate at which she commutes per day.

Mathematically, this equals 14/3.5 = 4 days

12
