The table below shows that 1 day equals 24 hours. notice that 12 hours is one-half of that. use the table to help you determine how many days are equal to 30 hours. 1 day 24 hours 12 hours 12 hours

a.1 and 1 over 4. days
b.1 and 1 over 2. days
c.1 and 3 over 4. days
d.2 days

Answer 1

the answer is 1 and 1/4 days, or choice A.

Answer 2

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.
