Answer:

a.1 and 1 over 4. days

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 + (6)/(24)


30 \ \text{hours} = 1 + (1)/(4)

Thus, 30 hours = 1 and 1 over 4 days

Hence option (a) is correct.
