After the first 20 minutes of laying down the cement, you had used 1/4 of the bag. What is the rate you are laying cement in bags per hour? What is the unit rate?

If you would like to know what is the rate you are laying cement in bags per hour, you can calculate this using the following steps:

20 minutes ... 1/4 of the bag

1 hour = 60 minutes ... x = ?

20 * x = 1/4 * 60

20 * x = 15 / 20

x = 15/20

x = 3/4 of the bag

Result: After 1 hour ( = 60 minutes) of laying down the cement, you will use 3/4 of the bag.

If you would like to know what is the unit rate, you can calculate this using the following steps:

20 minutes ... 1/4 of the bag

x minutes = ? ... 1 bag

20 * 1 = x * 1/4 / * 4

20 * 4 = x

x = 80 minutes

Result: After 80 minutes, you will use 1 bag.

3/4 of a bag per hour.

1 hour is equal to 60 minutes

1/4 of a bag is equal to 20 minutes

20 minutes times 3 is equal to 60 minutes.

1/4 times 3 is equal to 3/4.
