Answer 2

Given:

• Speed of child is 10 metre.
• Distance is 1 km.

Need To Find:

• Time taken by the child ?

Solution:

As we know that,

⋆ Time = Distance/ speed

Here,

• Distance = 1 km = 1000 m.
• Speed = 10 m.

Putting the values,

➜ T = 1000/10

➜ T = 100 sec.

Therefore,

• Time taken by the child is 1 min 40 sec.

[1 min = 60 sec]
