- 29 min

Best answer

**Answer: (3) 23 min**

**Explanation:-**

The average speed of the car = 69 km/hr

Time taken by car to reached Raipur from Sonagharh = 35 min = 35/60

= 7/12 hr.

The distance from Raipur to Sonaghrh = 69 x 7/12

= 40.25 km

If the average speed increased by 36 km/hr.

Then, the speed = 69 + 36

= 105 km/hr

Time taken by car to cover 40.25 km = 40.25/105

= 8.05/21

= 8.05 /0,383

= 0.3833 hr

1 hr = 60 min

Therefore, 0.3833 hr = 0.3833 x 60

= 23 min

Hence, the answer is (3) 23 min.
