Explanation:
Path forms a right-angled triangle with sides 15 km (East) and 8 km (South). Shortest distance = √(15² + 8²) = √(225 + 64) = √289 = 17 km.
Swetha starts from her office and walks 150 m towards south, then she turns right and walks 80 m and then she turns left and walks 60 m. She finally turns left and walks 280 m to reach a bank. What is the shortest distance between her office and the bank?
Explanation:
Vertical movement: 150 m South + 60 m South = 210 m South. Horizontal movement: 80 m West, then 280 m East = 200 m East. The shortest distance is the hypotenuse: √(210² + 200²) = √(44100 + 40000) = √84100 = 290 m.
Lopa and Kritika are sitting facing each other at the time of sunset. If Lopa's shadow falls on the right side of Kritika, then in which direction is Kritika facing?
Explanation:
At sunset, sun is in the west, shadows fall east. Lopa's shadow falls on Kritika's right. For Kritika's right to be east, Kritika must be facing north. (Lopa then faces south, and her shadow east falls on Kritika's right side.)
