//Add the 2 distances you know
1/2 + 3/8 = total
4/8 + 3/8 = total
7/8 = total
//Although Timmy is now 7/8ths of a mile from his starting position so no idea if he walks back or not
1/2 + 3/8 = total
4/8 + 3/8 = total
7/8 = total
//Although Timmy is now 7/8ths of a mile from his starting position so no idea if he walks back or not
total distance = 8miles
4/8=1/2
1st time covered 1/2
2nd time covered 3/8
hence=1/2+3/8
=7/8
4/8=1/2
1st time covered 1/2
2nd time covered 3/8
hence=1/2+3/8
=7/8
