Question

Eliza fell asleep at 9:35 pm. She awoke 8 hours 45 minutes later. What time did Eliza wake up at?

Answer 1

Answer:

Eliza wake up at 6 : 20 am

Step-by-step explanation:

Eliza fell asleep at 9:35 pm.

She awoke after 8 hour 45 minutes.

We have to calculate the time at Eliza wake up.

So we add 8 hour 45 minutes to 9:35.

After 8 hours time will be 5 : 35 am.

She takes 45 minutes more, so the time will be

5 : 35 am + 45 minutes = 6 : 20 am.

Answer 2

Eliza woke up at 6:20 am.

Given the following data:

• Time Eliza slept = 9:35 pm.

• Amount of time she slept = 8 hours 45 minutes.

To find what time Eliza woke up:

In this exercise, you're required to find the exact time when Eliza woke up after falling asleep at exactly 9:35 pm and waking up 8 hours 45 minutes later.

First of all, we would add the hours together;

$Hours = 9 + 8$

Hours = 17.

Next, we would add the minutes together;

$Minutes = 35 + 45$

Minutes = 80 minutes.

Conversion:

60 minutes = 1 hour

80 minutes = 1 hour 20 minutes.

$Wake \;up\; time = 17 + 1 + (20 \;minutes)\\\\Wake \;up\; time = 18 + (20 \;minutes)$

Note: 18 hours on the 24-hours clock is equivalent to 6 on the 12-hours clock.

Therefore, Eliza woke up at 6:20 am.
