Ms. tao flies roundtrip twice yearly between jacksonville and los angeles on business the distance between the two cites is 2,150 miles. estimate the distance she flies for both trips, then find the exact distance

2,150 estimated would be 2,000. Since she flies there and back multiply 2,000 by 2. Since she flies it twice multiply 4,000 by 2. Estimated: 8,000 miles. To find the exact miles Do the same thing but with 2,150: 2,150 times 2 = 4,300. 4,300 times 2 = 8,600. She flies exactly 8,600 miles per year :)
