Math Equation Response Question
Gary is weeding his vegetable garden.
It takes him 45 seconds to weed 3 square feet.
The vegetable garden is in the shape of a rectangle that is 4 yards by 6 yards.
How many MINUTES will it take Gary to weed his entire vegetable garden?
Use the on-screen keyboard to type the answer in the box below
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.
