Final answer:
Joe mows at a rate of 0.6 lawn per hour. Multiplying this rate by 6 hours, we find that Joe can mow 3.6 lawns in 6 hours.
Step-by-step explanation:
To answer the question, we need to calculate Joe’s rate of mowing lawns per hour and then use that rate to determine how many lawns he can mow in 6 hours. First, we find Joe's rate. Since Joe mowed 1 1/2 lawns in 2 1/2 hours, we divide the number of lawns by the number of hours to find the rate per hour.
Rate = ⅔ of a lawn / hour = 0.6 lawn / hour.
Next, to find out how many lawns Joe can mow in 6 hours, we multiply his rate per hour by the total number of hours.
Lawns in 6 hours = 0.6 lawn/hour × 6 hours.
Joe can mow 3.6 lawns in 6 hours.
