Question

Timmy went out for a walk. He walked 1/2 of a mile and then sat down to rest. After a few minutes. Timmy got up and walked 3/8 mile. How far did he walk in total?

Answer 1

//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

Answer 2

Total distance = 8miles
4/8=1/2
1st time covered 1/2
2nd time covered 3/8

hence=1/2+3/8
         =7/8
