Question

7 hours and 30 minutes is equivalent to

• A. 7.30 hours
• B. 7.5 hours
• C. 7.25 hours
• D. 7 hours

Answer 1

Answer: (B)

7.5 hours

60 minutes = 1 hour
1 minute = $\frac{1}{60}$ hour
$\text{Therefore 30 minutes =}\frac{1}{60}\times 30\text{= 0.5 hours}$
So, 7 hours and 30 minutes is
7+ 0.5 = 7.5 hours
