Explanation:

For Question 15:

Step1: Estimate distances first

Round values: $459 \approx 460$, $644 \approx 640$

Step2: Calculate estimated difference

$640 - 460 = 180$

Step3: Find exact difference

$644 - 459 = 185$

Step4: Verify reasonableness

185 is close to the estimate 180, so it is reasonable.

Step1: Calculate Rudy's total trip

$459 + 387 = 846$

Step2: Identify Luis's trip distance

Luis's distance = 644 miles

Step3: Find the difference

$846 - 644 = 202$

Answer:

a. Estimated answer: 180 miles
b. The distance from Dallas to Omaha minus the distance from Chicago to Omaha equals how many miles closer Chicago is to Omaha than Dallas.
c. The exact answer of 185 miles is close to the estimated 180 miles, so the answer is reasonable.
Final exact answer: 185 miles
