Answer 1

Cat sleeps 420 hours than Alice in a month

Explanation:

Given:

Number of hours Alice sleeps per night = 9 hours

Number of hours Cat sleeps per night = 20 hours

To Find:

How many more hours does a cat sleep in 1 month that Alice

Solution:

Let

The total number of hours for which Alice Sleeps in one month be x

The total number of hours for which Cat sleeps in one month be y

Step 1: Number of hours for which Alice Sleeps in one month

X = number of days in a month X Number of hours Alice sleeps per night

X = 30 X 9

X = 180 Hours

Step 2: Number of hours for which Cat Sleeps in one month

y= number of days in a month X Number of hours cat sleeps per night

y = 30 X 20

y = 600 Hours

Now ,

=> y – x

=>600 – 180

=>420 hours
