Fill in the blank:

The boring machine bores 211 ft in a day.
In 301 days, it will bore _____ ft.

• A. 62,611 ft
• B. 63,611 ft
• C. 63,511 ft
• D. 66,511 ft

Answer 1

The correct option is C 63,511 ft

The amount of material bored by the machine = 211 ft.

So, in 301 days, the amount of material $\text{bored will be}=211\times 301\text{ft.}$

Now, lining the numbers and right-aligning them, we get:


So, the machine will bore 63,511 ft in 301 days.
