Step-by-step explanation:
Every day at work, Kay walks up 9 flights of stairs. If there are 13 steps in 1 flight of stairs, how many steps does Kay climb in 5 days at work?
The number of steps she walks in a day will be:
= 13 steps × 9
= 117 steps
Number from steps in 5 days will be:
= 117 steps × 5
= 585 steps
If you sleep 7 hours every night how many hours are you AWAKE in a year?
The number for hours awake in a day will be:
= 24 hours - 7 hours
= 17 hours
The number for hours awake in a year will then be:
= 17 hours × 365
= 6205 hours
