To find out how many questions Rachel answers in one minute, we need to divide the number of questions she answered in 15 minutes by the number of minutes.
7 12 questions / 15 minutes = 4/5 of a question
Therefore, Rachel answers approximately 4/5 or 0.8 of a question in one minute.
To calculate how many questions Rachel answers in one minute, divide the total number of questions she answered (7) by the total time she took (15 minutes):
7 questions / 15 minutes = 0.4667 questions per minute
So, Rachel answers approximately 0.4667 questions in one minute.
To find out how many questions Rachel answers in one minute, we can use the information given. We know that in 15 minutes, she finished 7 and 12 questions.
To find out how many questions she answers in one minute, we can set up a proportion.
15 minutes = 7 12 questions
1 minute = x questions
To solve for x, we can use cross-multiplication.
15 * x = 1 * 12
Multiplying both sides, we get:
15x = 12
To isolate x, we divide both sides by 15:
x = 12 / 15
Simplifying the fraction, we get:
x = 4 / 5
So Rachel answers 4/5 (or 0.8) of a question in one minute.
Therefore, the answer is that Rachel answers approximately 0.8 of a question in one minute.
