Answer 1

First, calculate the area of the vegetable garden in square feet. Remember that 1 yard is equal to 3 feet.

Area = length * width
Area = (4 yards * 3 feet/yard) * (6 yards * 3 feet/yard)
Area = 12 feet * 18 feet
Area = 216 square feet

Next, calculate how long it takes Gary to weed 1 square foot.

Time per square foot = 45 seconds / 3 square feet
Time per square foot = 15 seconds/square foot

Finally, multiply the time per square foot by the total area of the garden and convert the result to minutes.

Total time = (Time per square foot) * (Area)
Total time = 15 seconds/square foot * 216 square feet
Total time = 3240 seconds
Total time = 3240 seconds / 60 seconds/minute
Total time = 54 minutes

Therefore, it will take Gary 54 minutes to weed his entire vegetable garden.
