I don't know how your son is supposed to do this.
Here's a simple algebra solution. Let x = the miles that Jan and Myra each ran.
x + x + x  8 = 64
3x  8 = 64
3x = 64 + 8
3x = 72
x = 72/3
x = 24
24  8 = 16

this makes no sense to me and won't to my child either. the instructions for solving, are try 3 numbers that add to the total with 2 numbers equal and the other 8 less then revise numbers till you get the answer.
