Answer 1

Hi.

Good Question and Keep progressing

Here is your answer----

__________________________________________
__________________________________________

Given---
       
           In 1 minute distance covered by the Sunita is 1/25 km.
Thus,
          Distance of 1/25 km is covered by the Sunita in 1 minute
Therefore,
          Distance of 1 km------------------------------------------ 1/(1/25) minutes
Thus,
         Distance of 3 km-------------------------------------------25 x 3 minutes
                                                                                       = 75 minutes.
                                                                                       (75 x 60 seconds)
                                                                                       (4500 seconds)

The time taken by the Sunita to cover a distance of 3 km is 75 minutes(or 4500 seconds).
