Think and answer
a man walks at a speed of 1 m/s and covers a certain distance in some time. but, if he walks at a
speed of 3 m/s, he covers an additional distance of 15 m in the same time. what is the distance ne
actually covered?
2. a child walks 5 m straight from his house, then turns left and walks 12 m. he then walks 13 m
straight back to his house. what is his displacement?
