Kisan is digging a hole in his backyard at a constant rate. After 3 hours, the hole has reached a depth of -12ft . Kisan uses the problem (-12) /(3) to determine the depth reached in an hour.

Answer 1

To determine the depth reached in an hour, Kisan divides the total depth by the time taken.

He has dug a hole to a depth of -12 feet after 3 hours. To find the rate at which he is digging per hour, we can calculate:

\[ \text{Depth per hour} = \frac{-12 \text{ ft}}{3 \text{ hours}} = -4 \text{ ft/hour} \]

This indicates that Kisan is digging at a rate of -4 feet per hour, meaning he is digging downwards into the ground.
