Question

Mr. Lockhart is digging a trench to put in the new school sprinkler system. Every 1/4 hour,

the length of his trench increases by 2/3 foot. By how much does the length, in feet, of
Mr. Lockhart's trench increase each hour?

Answer 1

The answer to this question is 2 and 2/3

Answer 2

`(8)/(3)` ft. (2.67 ft.)

Explanation:

We know that every 1/4th of an hour, the trench increases by 2/3 of a foot. To find how large the trench is in an hour, we simply multiply 2/3 by 4.

`x=((2)/(3))((4)/(1))`

`x=(8)/(3)`

If we want to find the value without being in a fraction, divide 8 by 3.

`x=(8)/(3)`

`x=2.67`
