Question

an athlete runs around a rectangular track of dimensions 20 m × 15m. Find his distance and displacement after completion of half round.

Answer 1

Answer:

Distance 300 and displacement 150

Answer 2

Answer:its distance covered will be perimeter/2 = 70/2

             =35m

its displacement will be 25m( for displacement we will have to find the half point of the rectangle which will be at the diagonal of the rectangle and hence it will be a right triangle . by applying h²=b²+p² which is

h²=20²+15² we wil get 25m )
