Best answer
Correct Answer - Option 3 : 12

Given:

Speed of bus = 45 km/hr

Distance covered by bus in 1 hour including stoppages = 36 km

Calculation:

Time taken to cover 45 km = 60 mins

So, Time taken to cover 36 km = (60/45) × 36 mins

⇒ 48 mins

Bus stopped for = (60 – 48) mins

⇒ 12 mins

∴ The bus stopped for 12 mins in an hour
