Renu will take 12 hours to cover distance of 100 Km.
Steps :-
Renu rides @ 10km/h
and stops for 10 mins after completing every 15 Kms.
So,
Total minutes for which renu took rest during the journey of 100 Km is 10 minutes in every 15 Kms. So,
10 × 6 = 60.
(Means Renu will take rest for 6 times during journey and will cover 90 kms of distance. After that only 10 km will remain and it will be covered without taking rest bcoz rest is to be taken after 15 kms.)
Now,
Suppose if renu travels without taking rest then she would have covered 100 km of distance in 10 Hours but she has taken rest of 1 hours during journey of 90 Km. So she has covered 90 Kms in 10 + 1 hours = 11 hours.
Now,
The remaining 10 km will be covered in 1 more hours so,
10 + 1 + 1 = 12 hours
Hope it will help u
