b) 10 yards per hour
c) 12 yards per hour
d) 15 yards per hour

Answer 1

To find the number of yards painted per hour, we need to convert the given information from inches to yards and minutes to hours. The number of yards painted per hour is 16.

Step-by-step explanation:

To find the number of yards painted per hour, we need to convert the given information from inches to yards and minutes to hours.

1. 720 inches is equivalent to (720/36) yards because there are 36 inches in a yard. So, 720 inches = 20 yards.
2. 75 minutes is equivalent to (75/60) hours because there are 60 minutes in an hour. So, 75 minutes = 1.25 hours.
3. To calculate the number of yards painted per hour, we divide the yards painted by the time in hours: 20 yards / 1.25 hours = 16 yards per hour.

Therefore, you are painting 16 yards per hour.
