sir hindi medium me solution dikha hi nahi rha hai (Question: 197003.0 )

please provide soln in both medium and don't waste my time.

Question:
A man rides a horse at the rate of 45 kms/hr and stops for 12 mins to change horse after every 12 kms. total time taken by him to cover a distance of 180 km is –
Options:
A) 6 hours 12 mins
B) 6 hours 48 mins 
C) 6 hours 36 mins 
D) 7 hours 24 mins
Solution:
Ans: (b) Number of stoppages = \(\cfrac{180}{12}\) – 1 = 14

\(\therefore\) Total time = \(\left ( \cfrac {180}{45} \right )\) hours + 12 ×14 min

                   = 4 hours + 168 min

                   = 6 hours 48 min
