Question

In digging a hole, the construction crew records the location of the bottom of the hole relative to ground level. In the first 3 hours, the crew digs at a rate of -2.75 feet each hour.​

Part A: How many feet would the crew record after 3 hours? Write an expression representing this situation.

Answer 1

Answer: 8.25 feet below ground level.

Step-by-step explanation: To calculate the depth of the hole after 3 hours, we can use the following expression:

depth = -2.75 * 3

The negative sign indicates that the crew is digging downwards. The rate of digging is 2.75 feet per hour and the crew has been digging for 3 hours. Therefore, the depth of the hole after 3 hours would be 8.25 feet below ground level.

I hope this helps!
