Answer:
120 hours
Explanation:
To find out how many hours Harry will study in 30 days, we need to calculate the total number of hours he will study in one day and then multiply it by the number of days (30 days).
Harry studies 28 hours per week, and there are 7 days in a week. So, his average daily study hours are:
Average daily study hours = 28 hours / 7 days = 4 hours per day
Now, to find the total hours he will study in 30 days:
Total study hours in 30 days = Average daily study hours × Number of days
Total study hours in 30 days = 4 hours per day × 30 days
Total study hours in 30 days = 120 hours
Harry will study 120 hours in 30 days.
