Answer:
a.1 and 1 over 4. days
Step-by-step explanation:
Since 1 day = 24 hours
⇒ 24 hours = 1 day
⇒ 1 hour = 1 ÷ 24 day.
Now, 30 hours = (24 + 6)hours
⇒ 30 hours = (24 + 6) ÷ 24 days
⇒ \(30 \ \text{hours} = 1 + \frac{6}{24}\)
⇒ \(30 \ \text{hours} = 1 + \frac{1}{4}\)
Thus, 30 hours = 1 and 1 over 4 days
Hence option (a) is correct.
