Question

A train is going on a journey. First it travels east for 50 kilometers. Then it turns north and travels for 22

Answer 1

The train travel 20 kilometers in the southward direction to reach its original location.

Step-by-step explanation:

          The given is,

                First train travels east for 50 kilometers, then

                Turns north and travels for 22 kilometers

                 It goes west for 50 kilometers

Step:1

       Let, A - Distance of train travels from its starting point in Eastern direction at pq point

              B - Distance train travels in northward direction at qr point

              C - Distance of train travels in western direction at rs point

              D - Distance of train travels in southward direction to reach its starting location at sp point

Step:2

           Refer the attachment,

           Distance of travel in northward direction and distance of travel in southward direction are equal.

           qr = sp.............. (1)                           ( ∵ Eqn (1) from the Diagram)

           20 km = 20 km

          sp = 20 km

Result:

       So, the distance of train travel to reach its original location in southward direction is 20 km.
