Let's analyze and solve the problem in the image.

Problem Breakdown

1. The table shows the relationship between Time (minutes) and Pages Read. Given values are:

   • 50 minutes corresponds to 60 pages.
   • 80 minutes corresponds to 96 pages.

2. We need to:

   • (a) Fill in the red boxes by determining the multiplicative relationship.
   • (b) Find out how many pages Thomas can read in 30 minutes.

Solution

Part (a): Filling in the Multiplicative Relationship

1. To find the pages per minute rate:

   • Since Thomas reads 60 pages in 50 minutes, we calculate the rate as: $\text{Rate} = \frac{60}{50} = 1.2 \text{ pages per minute}$

2. Using this rate, let’s fill in the red boxes:

   • First row: $50 \times 1.2 = 60$
     • So, the multiplier in the first row is $1.2$.
   • Second row: We know 80 minutes corresponds to 96 pages. Dividing to check the rate: $96 \div 1.2 = 80$
     • So, the divisor in the second row is $1.2$.

Thus, the completed table should show:

• Multiplier for the first row is $1.2$.
• Divisor for the second row is $1.2$.

Part (b): Calculating Pages in 30 Minutes

1. Using the rate of 1.2 pages per minute, the number of pages Thomas can read in 30 minutes is: $30 \times 1.2 = 36 \text{ pages}$

Answers

• (a) Fill in the table with 1.2 as the multiplier (for 50 to 60 pages) and divisor (for 80 to 96 pages).
• (b) Thomas can read 36 pages in 30 minutes.

Related Questions for Practice:

1. If Thomas read for 100 minutes, how many pages would he read?
2. How many minutes would it take Thomas to read 72 pages?
3. If Thomas’s reading rate increased to 1.5 pages per minute, how many pages could he read in 50 minutes?
4. What would Thomas’s reading time be if he read 120 pages at the rate of 1.2 pages per minute?
5. How would the answers change if Thomas read only 0.8 pages per minute?

Tip:

When dealing with rate problems, always start by finding the unit rate, as it simplifies calculations for other amounts.
