To find the unit rate, divide the time it took to mow a part of the lawn (12 hours) by the amount of lawn mowed in that time (23).
Unit rate = (Time taken to mow part of the lawn)/(Amount of lawn mowed in that time)
Unit rate = 12 hours / 23
So the unit rate is approximately 0.5217 hours per 1 unit of lawn mowed.
To find how long it will take to mow the entire lawn, multiply the unit rate by the total amount of lawn.
Total time = Unit rate * Total amount of lawn
Total time = 0.5217 hours per unit * 1 unit (since the entire lawn is 1 unit)
Total time to mow the entire lawn is approximately 0.5217 hours.
Therefore, the correct answer is 1/2 or 1/3 of an hour.
