Question

Suppose you are staying in a hostel and you have to enter the details of your studies on an online portal on daily basis. But there is one problem, the portal takes input only in hours. If you have studied for 5 hours and 15 minutes, how will you enter the number of hours studied in the portal?

• A. 5.25 hours
• B. 5.15 hours
• C. 6.50 hours
• D. 4.85 hours

Answer 1

The correct option is A

5.25 hours

60 minutes = 1 hour

1 minute = $\frac{1}{60}$ hour

15 minutes = 15 $\times$ $\frac{1}{60}$ = 0.25 hour

So, 5 hours and 15 minutes = (5 + 0.25) = 5.25 hours
