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 generally need more sleep than adults. If they wake up at the same time, to get enough sleep (more than adults' 8 - hour requirement), they need to go to bed earlier. 1 - 2 hours earlier is a reasonable estimate considering the sleep - need difference.

Answer:

1 to 2 hours earlier
