I am still learning, and am most likely incorrect.

I believe you remove the 3's since their not needed, and do this:

2x = 4x + 6 - (2x)

so then just ignore "x" and do this:

2 = 4 + 6 - 2

2 = 10 - 2

2 = 8

x = 8

Runner A crosses the starting line of a marathon and runs at an average pace of 5.6 miles per hour. Half an hour later, Runner B

marishachu [46]

Time it took runner A to complete the marathon = 26.2 / 5.6 = 4 hrs 41 mins
Time it took runner B to complete the marathon = 26.2 / 6.4 = 4 hrs 6 mins

Time it took runner B to complete the marathon relative to when runner A started = 30 mins + 4 hrs 6 mins = 4 hrs 36 mins

Therefore, runner B will finnish ahead of runner A.

Let x be the time the two runners are at the same point, then
5.6x + 5.6(0.5) = 6.4x
6.4x - 5.6x = 2.8
0.8x = 2.8
x = 2.8/0.8 = 3.5
Therefore, runner B will catch up with runner A 3.5 hours after runner A starts the race.
Runner B; Runner B will catch up to Runner A 3.5 hours after Runner A crosses the starting line.
