Question

. A train runs 120 km in West direction, 30 km in South
direction and then 80 km in East direction before reaching
the station. In which direction is the station from the
train's starting point?​

Answer 1

The train is 50 km south -west of its strting point

1. You need to draw the lines or the diagram as the direction of train.
2. So,now as train goes 120km in west ,30 km in south and again 80 km in east direction, connect the points from where it starts to where it ends.
3. You will get a right angle triangle so now we know two sides of that triangle i.e. 30km and 40 km. So,now using Pythagoras theorem we get distance as 50km south-west.

Answer 2

Answer:

The train is 50 km south -west of its strting point

You need to draw the lines or the diagram as the direction of train.

So,now as train goes 120km in west ,30 km in south and again 80 km in east direction, connect the points from where it starts to where it ends.
