Question

5 hours and 15 minutes is equivalent to

• A. 5.15 hours
• B. 5.25 hours
• C. 5.30 hours
• D. None of the above

Answer 1

The correct option is B 5.25 hours

60 minutes = 1 hour
1 minute = $\frac{1}{60}$ hour
$\text{Therefore 15 minutes =}\frac{1}{60}\times 15\text{= 0.25 hours}$
So, 5 hours and 15 minutes is
5 + 0.25 = 5.25 hours
