It takes one day for a builder to dig a 2m by 2m by 2m hole. How long does it take 3 builders working at the same rate to dig a 4m by 4m by 4m hole? (please include the solution)

You are remodeling your kitchen. you’ve contacted two tiling companies who gladly told you how long it took their workers to tile of a similar size jim completed half the floor in 8 hours. pete completed half of the other floor in 7 hours. if pete can lay 20 more tiles per hour than jim, at what rate can jim lay tiles
