(256222)for an object that travels 20 kilometers north and then 15 kilometers south, what is the ratio of the distance traveled to the displacement?

assuming north as positive direction and south as negative direction of motion

y = path travelled in north direction = 20 kilometer

y' = path travelled in south direction = - 15 kilometer

distance travelled is given as

distance = d = |y| + |y'| = 20 + 15 = 35 kilometer

displacement is given as

displacement = D = y + y' = 20 + (-15) = 5 kilometer

Ratio of distance travelled to displacement is given as

Ratio = d/D = 35/5 = 7

Ratio = 7:1

555.99.
