Question

Convert 45 minutes 30 seconds to hours

• A. 0.758 hours
• B. 0.66 hours
• C. 0.58 hours
• D. 0.9 hours

Answer 1

The correct option is A

0.758 hours

1 minute = 60 seconds
45 minutes = $45\times 60$
= 2700 seconds
45 minutes 30 seconds = 2700+30 = 2730 seconds
1 hr = 3600 seconds
1 second =$\frac{1}{3600}$ hr
2730 seconds = $\frac{273\text{/}0}{360\text{/}0}$
= 0.758 hours
