A lawn is 10,000 sq. feet. Ken can mow 1/4 of the lawn in 1/5 of an hour. Katie can mow 3/5 of the lawn in 2/6 of an hour. a) Who mows the entire lawn faster?

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

221,500 is the answer
