Final answer:
Kelly spends 25 minutes per chore which is 5/12 of an hour. The provided answer choices do not include 5/12, suggesting an error in the question's options.
Step-by-step explanation:
The student, Kelly, has 1 1/4 hours to complete 3 chores before leaving for soccer practice. To find out how long she spends on each chore, we first convert 1 1/4 hours to minutes. 1 hour is 60 minutes, so 1 1/4 hours is 60 minutes + (1/4 of 60 minutes). A quarter of an hour (15 minutes) added to 60 minutes is 75 minutes in total. Then, we divide those 75 minutes equally among the 3 chores. Doing the division, 75 minutes ÷ 3 equals 25 minutes per chore. To express this answer as a fraction of an hour, remember that Kelly had 1 1/4 hours, we know that there are 60 minutes in 1 hour. Hence, 25 minutes is less than half an hour. Therefore, 25 minutes is 25/60, which when simplified is 5/12 of an hour for each chore.
However, the options provided (A) 1/4 (B) 1/3 (C) 3/4 (D) 1/2 do not include 5/12. It seems there may have been an error in the question or the answer choices, as none match the correct calculation.
