A bank employee drives 10 km towards South from her house and turns to her left and drives another 20 km. She again turns left and drives 40 km, then she turns to her right and drives for another 5 km. She again turns to her right and drives another 30 km to reach her bank where she works. What is the shortest distance between her bank and her house?
20 km
25 km
30 km
35 km
The route taken by the bank employee has been calculated below by converting all movements in hard directions from right-left: 1 - 10 km South 2 - 20 km East 3 - 40 km North 4 - 5 km East 5 - 30 km South Net movement = 25 km East Hence, the shortest distance between her house and her bank is 25 km. Hence, option (b) is the correct answer.
