<em>Missing Information:</em>

<em>It takes Mr. Hamilton 1/15  of an hour to grade one student’s exam and 1/30  of an hour to grade one  student’s quiz.</em>

Answer:

Total\ Time = \frac{x}{10}

Step-by-step explanation:

Given

Exam = \frac{1}{15}hr

Quiz = \frac{1}{30}hr

Required

Determine the time spent on x students

First, we need to determine the total time spent on 1 student

Time = Exam + Quiz

Time = \frac{1}{15} + \frac{1}{30}

Take LCM

Time = \frac{2 + 1}{30}

Time = \frac{3}{30}

Time = \frac{1}{10}

Next is to determine the total time on x students:

Total\ Time = \frac{1}{10} * x

Total\ Time = \frac{x}{10}
