How long do a son and father working together take to dig a garden 7 feet long and 5 feet wide if the father alone can do it in 3 hours and the son alone in 4 hours?

The dimensions of the garden are irrelevant to the solution In 1 hour the father can dig 1/3 of the garden, and the son can dig 1/4 of the garden Together in 1 hour they can dig 1/3 + 1/4 = 4/12 + 3/12 = 7/12 of the garden The whole garden will take 1 ÷ 7/12 hours = 12/7 hours = 1 5/7 hours = 1 hr 42 6/7 mins They will take slightly less than 1¾ hours to dig the garden together.
