2. Which situation can be represented by the equation \( 1 \frac{1}{4} \times 6=7 \frac{1}{2} \) ? A. It took Calvin \( 1 \frac{1}{4} \) hours to run 6 miles. He ran \( 7 \frac{1}{2} \) miles per hour. B. Sara read for \( 1 \frac{1}{4} \) hours every day for 6 days. She read for a total of \( 7 \frac{1}{2} \) hours. C. Matthew addressed \( 1 \frac{1}{4} \) envelopes in 6 minutes. He addressed \( 7 \frac{1}{2} \) envelopes per minute. D. It took Beth \( 1 \frac{1}{4} \) minutes to paint 6 foet of a board. She painted a total of \( 7 \frac{1}{2} \) feet of the board. What are the Key words in 3 that tell us it is multiplication?

In option C, the key words that indicate multiplication are "addressed" and "envelopes per minute." The use of the phrase "per minute" suggests that there is a rate involved, which implies multiplication of the amount of time by the rate of envelopes addressed. This shows how often an action occurs over a set time period, a classic scenario for using multiplication to find a total. Similarly, in option B, the key phrase "every day" signals a repeated action over a series of days. The way it states "1 ¼ hours every day for 6 days" highlights the need to multiply the time spent reading each day by the total number of days to arrive at the overall reading time, making multiplication a key part of illustrating the total.
