Sagot :
As you said the distance from your home to your barangay hall is 450 meters and from your barangay hall to your school is 350 meters. If you pass through the hall on your way to school from your home, you just have to add both distances (450 & 350) to get the answer to your question. The answer is 800 meters.
To find out how far you have traveled:
450 m+350 m=800 m
Hope this helps =)
450 m+350 m=800 m
