PLZ PROVIDE ANSWER WITH EXPLANATION.​

Answer 1

Answer:

10 km

Step-by-step explanation:

Amrita walks 8 km in the south

She then walks 10 km north

Then she walks 2 km more in the north from her house after one round,

So she will be 2 km * 5 = 10 km away from her home after five rounds.

Answer 2

Answer: 10 km in North direction

Step-by-step explanation:

Amrita goes 8 km towards South from her home and then 10 km in North.

So she went 2 km North from her home after the first round.

Now we can say that after each round she will go 2 km more in North direction.

If she goes 2 km North in one round then we can easily write-

        2 km North - after 1 round

        4 km North - after 2 rounds

        6 km North - after 3 rounds  

        8 km North - after 4 rounds

        10 km North - after 5 rounds        

So after 5 rounds she will be at distance of 10 km North from her home.
