Example 4 SOLUTION Draw a diagram. Then use the Pythagorean theorem to find each distance from the Washington Block. Using Irrational Numbers Landmark Buildings Your class is visiting historical landmarks in Chicago. Outside the Washington Block, you break up into two groups. Group A walks about 800 meters east and 200 meters south to the Chicago Building. Group B walks about 600 meters south and 200 meters east to the Rookery Building. To the nearest 10 meters, how much farther is group A from the Washington Block than group B is?
Group A: = + 2002 8002 680,000 ≈ 825 Group B: + 2002 6002 = 400,000 ≈ 632 Difference in distances: 825 – 632 = 193 ANSWER To the nearest 10 meters, group A is about 190 meters farther from the Washington Block than group B is. Example 4 Using Irrational Numbers
