Problem: A local business donates 482 children's books to 8 elementary schools. If the books are distributed among the schools as equally as possible, approximately how many books will each school receive?

It takes Suzie 2 hours to walk 3.5 miles. At this rate, how many miles can Suzie walk in 3 hours?

Rationale

Suzie can walk approximately 5.25 miles in 3 hours.

To determine how far Suzie can walk in 3 hours, we first find her walking rate by dividing the distance she walks by the time it takes. Suzie walks 3.5 miles in 2 hours, giving a rate of 1.75 miles per hour. Over 3 hours, this rate allows her to cover about 5.25 miles.

A (1.75 miles) YOUR ANSWER

This option reflects Suzie's walking rate per hour rather than the total distance covered over 3 hours. While she can walk 1.75 miles in one hour, it does not account for the additional time available.

B (4.5 miles) YOUR ANSWER

This distance does not align with the calculations based on Suzie's walking rate. At 1.75 miles per hour, walking for 3 hours would yield 5.25 miles, making this option incorrect.

C (5.25 miles) CORRECT

This is the correct answer, calculated from Suzie's speed of 1.75 miles per hour multiplied by 3 hours (1.75 miles/hour * 3 hours = 5.25 miles). This accurately reflects the distance she can cover in the given time.

D (5.5 miles) YOUR ANSWER

While this distance is close, it exceeds the calculated distance of 5.25 miles. Based on the rate derived from her initial walk, Suzie's actual distance in 3 hours cannot reach 5.5 miles.

Conclusion

To summarize, Suzie’s walking efficiency allows her to cover approximately 5.25 miles in 3 hours based on a consistent pace of 1.75 miles per hour. The other options do not reflect the appropriate calculations derived from her walking rate over the specified duration, making 5.25 miles the only accurate answer.

It takes Suzie 2 hours to walk 3.5 miles. At this rate, how many miles can Suzie walk in 3 hours?

Suzie can walk approximately 5.25 miles in 3 hours.
