Given:

Speed of the car = 80 km/hr

Time taken to complete the journey = 9 hours

Speed of the car for the same distance = 60 km/hr

Formula Used:

Distance = Speed × Time

Time = Distance / Speed

Calculation:

Distance travelled = 80 km/hr × 9 hrs

Distance travelled = 720 km

Time required to travel 720 km at 60 km/hr

⇒ Time = 720 km / 60 km/hr

⇒ Time = 12 hours

The correct answer is option 3.
