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

Answer: C

Explanation:

Suzie can walk approximately 5.25 miles in 3 hours.

At her current walking rate, Suzie would cover about 5.25 miles in 3 hours. This is determined by calculating her speed and then extrapolating that over the given time frame.

A) 1.75 miles

This option is incorrect because it suggests a distance that is significantly less than what Suzie can cover in 3 hours. Given that she walks 1.75 miles in 2 hours, she would not be able to only walk this distance in 3 hours.

B) 4.5 miles

While 4.5 miles is a reasonable distance, it underestimates Suzie's capability based on her walking rate. In 3 hours, her speed allows her to walk more than this distance, making this option incorrect.

C) 5.25 miles

This is the correct answer. To find how far Suzie can walk in 3 hours, we first determine her walking rate, which is 3.5 miles in 2 hours, or 1.75 miles per hour. Over 3 hours, she would cover 1.75 miles/hour * 3 hours = 5.25 miles.

D) 5.5 miles

This option is incorrect because it slightly overestimates the distance Suzie can walk in 3 hours. Based on her calculated walking rate, she cannot reach 5.5 miles in the time provided.

Conclusion

The correct answer is 5.25 miles, as calculated from Suzie's walking rate of 1.75 miles per hour over 3 hours. Options A, B, and D fail to accurately reflect her walking capacity, making them incorrect choices.
