Question

If you have to represent 5 hours and 45 minutes in hours as decimals, how would you do it?

• A. 5.04 hours
• B. 5.45 hours
• C. 5.44 hours
• D. 5.75 hours

Answer 1

The correct option is D

5.75 hours

60 minutes = 1 hour

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

45 minutes = 45 × $\frac{1}{60}$
= $\frac{45}{60}$
= 0.75 hours

So, 5 hours and 45 minutes $=(5+0.75)=5.75$ hours
