Answer 1

Johnny slept 30.75 hours this week, which is calculated by multiplying last week's sleep time of 20.5 hours by 1.5.

Step-by-step explanation:

To calculate how many hours Johnny slept this week, we need to multiply the number of hours he slept last week by 1.5, as it is mentioned that he slept 1.5 times as many hours.

Last week Johnny slept 20.5 hours.

This week Johnny slept 1.5 times as many, which is calculated as follows:

20.5 hours × 1.5 = 30.75 hours.

Therefore, Johnny slept 30.75 hours this week.
