Answer: To calculate the hit rate metric in tons per hour, we need to first calculate how many tons of dirt the construction company can remove in one hour.
To do this, we'll convert the given time and amount of dirt into a rate of dirt removal in tons per hour:
The company takes 1 7/8 hours to remove 2 3/4 tons of dirt
We can convert 1 7/8 hours to an improper fraction: 15/8 hours
We can convert 2 3/4 tons to an improper fraction: 11/4 tons
We can calculate the rate of dirt removal as the amount of dirt divided by the time: (11/4 tons) / (15/8 hours) = (11/4) ÷ (15/8) = (11/4) x (8/15) = 22/15 tons per hour
Therefore, the construction company has a hit rate metric of 22/15 tons per hour, which simplifies to 1.47 tons per hour (rounded to two decimal places).
