Answer 2

Answer:

Nanu will take 15 days to catch up with Mika.

Step-by-step explanation:

Let 'x' be the day on which Nanu catches up with Mika after Mika starts the migration.

On the first day, Mika covers 150 km.By the second day he'll cover 300 km in all. By the xth day he'll cover 150x km.

On the fourth day after Mika started migration, Nanu would cover 180 km. By the end of the xth day he'll cover 180(x-3)km.

Then, 150(x) = 180(x-3) (as they cover the same distance by xth day and catch- up.)

So x = 18.

Hence Nanu catches up with Mika after 18 - 3, that is 15 days of travel.

(Note that Mika has travelled for 18 days and Nanu for 15 days.)
