my home. How many km did I travel?.​

Answer 1

Answer:

7km.

let the house be at O(0,0). then the point 4 km east will be E(4,0) and the present position will be W(-3,0). counting the unit boxes you get 7 units. therefore 7km travelled.

Answer 2

Answer:

4 kilometre from S3 should be added to 3 km from best because then we have to travel for kilometres to reach house and tree kilometre more to reach 3 kilometre for best 4 + 3 is equal to 7 if it helps you only a little bit then please mark it as brainlist
