Bob is tilling a plot of his garden. The plot is 110 feet wide by 120 feet long. His tiller digs a swath two feet wide, and he can till 1 foot of ground in about 2 seconds. How long will it take him to till this plot of land, in minutes?
If Bob goes along the side that's 120 feet long, he will till 110 / 2 = 55 rows.
Each of these rows are 120 feet long, so he will push the tiller a total of 120 * 55 = <<120*55=6600>>6,600 feet.
He tills 1 linear foot of ground every 2 seconds, so it will take him 2 * 6,600 = 13,200 seconds to till this plot
13,200 seconds is 13,2000 / 60 = <<13200/60=220>>220 minutes

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

A school library has 120 books.  Each student needs 5 books for their classes.  The library was able to help 4 students on the first day of school, 5 students on the second day and 6 students on the third day.  How many students can the library help out on the fourth day of school?On the first day, the library used 4 students * 5 books = <<4*5=20>>20 books.
On the second day, the library used 5 students * 5 books = <<5*5=25>>25 books.
On the third day, the library used 6 students * 5 books = <<6*5=30>>30 books.
On the fourth day, the library had 120 books - 20 - 25 - 30 = <<120-20-25-30=45>>45 books remaining.
The library can help 45 books / 5 books = <<45/5=9>>9 students on the fourth day.

Christi saw twice as many black bears as white bears and 40 more brown bears than black bears in a national park. If the number of black bears in the park is 60, calculate the population of bears in the park.If there are 60 black bears in the park and 40 more brown bears than black bears, there are 60+40 = <<60+40=100>>100 brown bears.
The number of black and brown bears in the park is 100+60 = <<100+60=160>>160
Twice the number of black bears as white bears means 60/2 = <<60/2=30>>30 white bears.
The population of bears in the national park is 30+160 = <<30+160=190>>190

Now, solve this next question in the style of the above examples:

Bob is tilling a plot of his garden. The plot is 110 feet wide by 120 feet long. His tiller digs a swath two feet wide, and he can till 1 foot of ground in about 2 seconds. How long will it take him to till this plot of land, in minutes?

### Response:
If Bob goes along the side that's 120 feet long, he will till 110 / 2 = 55 rows.
Each of these rows are 120 feet long, so he will push the tiller a total of 120 * 55 = <<120*55=6600>>6,600 feet.
He tills 1 linear foot of ground every 2 seconds, so it will take him 2 * 6,600 = 13,200 seconds to till this plot
13,200 seconds is 13,2000 / 60 = <<13200/60=220>>220 minutes
