Question

3
A baby bird learnt to fly 4 m on the first day. After
that it could fly double the distance each day. How
far could it fly in a week?​

Answer 1

First day flight of bird = 4m

It's doubles every day so....

Week=7days

Then...

1st day = 4m

2nd day = 8m

3rd day = 16m

4th day = 32m

5th day = 64m

6th day =128m

and so on 7th day = 256m

Hope it helps...
