Answer:
1.30 m is the total distance covered
10m is the displacement
Explanation:
because you walk 20 m and walk back 30m you covered the distance in 30m and the displacement is 10 because 20-30 is equals to 10 because 10 is the excess from the starting point
2.Time taken to cover 60 km = 1 hour. Time taken to cover 1 km = 1/60 hour.
