Ken: 1/4 of 10,000 sq. Feet is 232.25 mowed in 12 minutes (1/5 of an hour). Ken has 9,767.75 left to mow which he’ll need 8 hours and 24 minutes to finish. Katie: 2/6 of 10,000 sq. Feet is 557.41 mowed in 20 minutes (2/6 of an hour). so Katie has 9,442.59 of the lawn left to mow, it’ll take 5 hours and 20 minutes for Katie to finish. So Katie mows the lawn faster
