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

Answer:

$\frac{8}{3}$ ft. (2.67 ft.)

Step-by-step 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.

$x=(\frac{2}{3})(\frac{4}{1})$

$x=\frac{8}{3}$

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

$x=\frac{8}{3}$

$x=2.67$
