Karen wakes up at 6: 00 a. m. it takes her 1 1/4 hours to shower, get dressed, and comb her hair. it takes her 1/2 an hour to eat breakfast, brush her teeth, and make her bed. at what time will she be ready for school? how do you solve it

She will be ready at 7:45 am.
1 1/4 hour = 1 hour and 15 minutes ( 1 hour divided by four is 15 minutes per quarter)
adding that to the initial time of 6:00am you get the time to be 7:15am adding the 1/2  an hour which is 30 minutes. Your final answer is, she will be ready at 7:45am.
