MY FRIEND AND I STARTED SIMULTANEOUSLY TOWARDS EACH OTHER FROM TWO PLACES 10M APART. AFTER WALKING 30M , MY FRIEND TURNS LEFT AND GOES 10M, THEN HE TURNS RIGHT AND GOES 20M AND THEN TURNS RIGHT AGAIN AND COMES BACK TO THE ROAD ON WHICH HE HAD STARTED WALKING. IF WE WALK WITH THE SAME SPEED , WHAT IS THE DISTANCE BETWEEN US THIS POINT OF TIME ?
Answer :
Let name of friends = A and B
and
B is the friend , who turn as per the question
We can draw a diagram which shows the whole distance covered by
Here we have shown position of B , As after 30 m ( B' ) And after 10 m left ( B" ) and after 20 m right ( B"' ) And then after return on same road , when start walking ( B* ) .
So,
Total distance between ( A' ) and ( B* ) = 20 + 20 + 10 + 20 = 70 m ( Ans )
