Explanation Given data: The straight line distance is 5.2 -mile . The road is oriented at an angle of 25 ° north to east. The road turns to north 4.0 mi to finish the race. Explanation: Initially, the racer start from point “ A ” and run in a straight line of 5.2 -mile , then road is oriented at an angle of 25 ° north to east and again road turns due north for 4.0 mi to finish the race as shown in Figure 1. The distance traveled from point “ A ” to “ C ” results straight-line distance from the starting point to destination point. Find the value of AB . A B = ( 5.2 mi ) cos ( 25 ° ) = 4.7 mi Find the value of BD . B D = ( 5.2 mi ) sin ( 25 ° ) = 2.1 mi Modify Figure 1 as shown in Figure 2
