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?

Answer 1

First, convert the dimensions of the vegetable garden from yards to feet. Since 1 yard is equal to 3 feet, the garden is 4 yards * 3 feet = <<4*3=12>>12 feet by 6 yards * 3 feet = <<6*3=18>>18 feet.
Next, find the area of the vegetable garden by multiplying the length by the width: 12 feet * 18 feet = <<12*18=216>>216 square feet.
Then divide the total area of the garden by the area Gary can weed in 45 seconds: 216 square feet / 3 square feet/45 seconds = 8
Then convert the 8 45-second periods to minutes: 8 * 45 seconds/minute = <<8*45=360>>360 seconds / 60 seconds/minute = <<360/60=6>>6 minutes. Answer: \boxed{6}.
