A car travelled 60 km towards the north direction from a point A. From there, it travelled 100 km in the south direction. How far is the car from point A now?
40 km South
40 km North
160 km South
160 km North
Let's assume a car travelling toward North as positive and South as negative.
+60 + (- 100) = - 40. The car is 40 km South from point A.
