Suppose a student studies on Khan Academy for 2 hours daily.
Weekly Study Time
2×7=142 \times 7 = 142×7=14
The student studies 14 hours per week.
Monthly Study Time
14×4=5614 \times 4 = 5614×4=56
The student studies approximately 56 hours per month.
Yearly Study Time
56×12=67256 \times 12 = 67256×12=672
The student studies around 672 hours annually.
