I say 2.6 x 10^, but it says its wrong? What am I doing wrong.

**drwls**, Friday, January 9, 2009 at 12:51amFor one thing, your 10^ has no exponent.

The distance between the two cars decreases at 1760 km/h. They start out 4600 km apart. The pass each other at t = 4600/1760 = 2.61364 h. In that time, the Car leaving GA has travelled 2640 km. The car leaving VA has travelled 1960 km. Round that to two sig figs if you wish. If you do, that would be 2.6*10^3 km from GA, which may be what you meant. In that case I agree with you
