Question

the average adult needs about 8 hours of sleep each night. when should teens go to bed relative to adults if they wake up at the same time?
1 to 2 hours earlier
20 to 30 minutes earlier
20 to 30 minutes later
1 to 2 hours later

Explanation:

Teens typically need more sleep than adults (around 8 - 10 hours or more). If they wake up at the same time as adults, to get sufficient sleep, they should go to bed 1 to 2 hours earlier than adults. The other options (20 - 30 minutes earlier, 20 - 30 minutes later, 1 - 2 hours later) don't align with the sleep needs of teens relative to adults.

Answer:

1 to 2 hours earlier
