PLEASE HELP ASAP

A special piece of equipment is used at a construction site to dig holes. A hole is dug to a depth of 3.25 feet when the equipment hits rock. The progress slows to 5/8 feet per hour of digging. The depth of the hole must be at least 11 1/2 feet by the end of the day to stay on schedule.

What is the minimum amount of time the equipment must continue at its present rate to complete the hole on schedule?

Answer:

13 hours and 12 minutes

Step-by-step explanation:

you put 3.25 as a fraction which is 3 1/4. then I took 3 1/4 and misused it by 11 1/2. 23/2 - 13/4 = 8 1/4

then we took the 5/8 and divided it by 33/4 (3 1/4)

I got 13 1/5.

13 1/5 is 13 hours and 12 minutes.
