Final answer:
To find the unit rate, divide the amount of dirt dug by the time taken. In this case, the backhoe can dig 510 of a ton of dirt in 16 of a hour. Therefore, the unit rate is 31.875 of a ton of dirt per hour.
Step-by-step explanation:
To find the unit rate, divide the amount of dirt dug by the time taken.
In this case, the backhoe can dig 510 of a ton of dirt in 16 of a hour.
To calculate the unit rate, divide 510 by 16: 510 ÷ 16 = 31.875.
Therefore, the unit rate is 31.875 of a ton of dirt per hour.
