**dawn**, Wednesday, April 7, 2010 at 9:58amrunner A runs 5.6 miles/hr so it will take him 4.68 hrs to run the marathon.

runner B runs 6.4 miles/hr so it will take 4.09 hrs to run the marathon

however runner B started half and hour later than runner A 4.68 - .5 = 4.18

so runner B will finish the marathon .09hrs before runner A

**Reiny**, Wednesday, April 7, 2010 at 9:59amrunning time of faster runner = 26.2/6.4 or 4.125 hours or 4:7.5

running time of slower runner = 26.2/5.6 or 4.67857 hours or 4:40.7

remember the faster runner started 30 minutes later, so what do you think?
