Question

required 0 21. a construction company is digging an area before building a house. they have been digging for 12.5 hours and are at a depth of -6 feet. if they keep digging at the same rate, how much longer will it be until they have dug another 11 feet, rounded to the nearest hour?

Answer 1

To determine how much longer it will take for the construction company to dig another 11 feet, we need to calculate their digging rate and then divide the distance by the rate.

Step-by-step explanation:

To find out how much longer it will be until the construction company has dug another 11 feet, we need to determine the rate at which they are digging.

They have been digging for 12.5 hours and are at a depth of -6 feet. Since they are digging at a constant rate, we can calculate their rate of digging by dividing the depth (-6 feet) by the time (12.5 hours). This gives us a rate of -0.48 feet per hour.

To determine how much longer it will take for the construction company to dig another 11 feet, we need to calculate their digging rate and then divide the distance by the rate.

Next, we can calculate the time it will take for them to dig another 11 feet by dividing the distance (11 feet) by the rate (-0.48 feet per hour). This gives us a time of -22.92 hours, which we can round to the nearest hour, resulting in an answer of -23 hours.
