Question
A puppy was trying to find its mother. It was facing East and walked 10 m in that direction. It then turned South and walked another 10 m. Then, it started walking towards North and walked 20 m. Then, it turned West and walked 10 m and then, moved 2 m South. In which direction and how far is it from the original position?radio_button_uncheckedNorth-East, 60 mradio_button_uncheckedNorth-East, 10 mradio_button_uncheckedNorth, 8 m radio_button_uncheckedNorth, 25 m
Solution
The puppy started at a point and moved as follows:
- East 10 m
- South 10 m
- North 20 m
- West 10 m
- South 2 m
After the first two steps, the puppy is 10 m East and 10 m South of the starting point.
After the third step, the puppy is 10 m North of the starting point (because it moved 20 m North from 10 m South).
After the fourth step, the puppy is back at the starting point (because it moved 10 m West from 10 m East).
After the fifth step, the puppy is 2 m South of the starting point.
So, the puppy is 2 m South of the starting point. The correct answer is not listed in the options.
