Answer 2

Answer:

Displacement = 200m

Explanation:

Time taken to complete 1 rounds = 20 s

1 minute 10 seconds = 70 seconds

Number of rounds that can be completed in 70 seconds = 70/20 = 3.5 rounds

Distance travelled = circumference of circle = 2 pie r

Diameter= 200

Radius= 100

Distance travelled = 2 *3.14*100*3.5 = 2198

Displacement = Shortest distance travelled

3 rounds = Displacement = 0 , as initial and final point is same.

Now, 0.5 = half round = diameter of ground = 200 m

Thus, displacement = 200 m.
