Question

writing for his school newspaper has helped darnell learn to type. he can type 50 words in 3 minutes.
complete the table.

minutes	3	\box	\box	18

graph the data from the table.

Explanation:

Step1: Find typing rate

First, calculate the words per minute rate.
$\text{Rate} = \frac{50}{3} \text{ words per minute}$
Or, equivalently, $\text{Time per word} = \frac{3}{50} \text{ minutes per word}$

Step2: Find time for 150 words

Use time per word to find total minutes.
$\text{Time} = 150 \times \frac{3}{50} = 9 \text{ minutes}$

Step3: Find time for 250 words

Calculate minutes for 250 typed words.
$\text{Time} = 250 \times \frac{3}{50} = 15 \text{ minutes}$

Step4: Find words for 18 minutes

Use words per minute to find total words.
$\text{Words} = 18 \times \frac{50}{3} = 300 \text{ words}$

Answer:

Completed table values:

• Minutes column (empty cells): 9, 15
• Words typed column (empty cell): 300

To graph the data:
Plot the coordinate pairs (3, 50), (9, 150), (15, 250), (18, 300) on the provided grid, with "Minutes" on the x-axis and "Words Typed" on the y-axis, then connect the points with a straight line.
