Answer 1

Answer:

sorry mujhe maths nhi ata

Answer 2

Man's speed = 4km/h

Time taken by man to reach playground = 30min = 0.5h

Formula : Speed = Distance/Time

Let Distance be x

4 = x/0.5

x = 2km

Now

Distance To Cover = 2km

Time Y wants to reach the distance in is 20 min = 1/3 h

Speed = Distance/Time

Speed = 2/(1/3)

Speed = 2 x 3

Speed = 6km/h
