450 km in 4 hour = 112.5 kmph
-15.5 = 97 kmph
Now to cover 873 => 873/97 = 9 hours = 540 minutes = 32400 seconds
= Option (7)

Initial Speed=450/4=112.5 kmph
New speed=112.5 - 15.5=97 kmph
So, time taken for 873 km = 873/97 = 9 hrs = 9x3600 sec = 32400 sec.

Initial velocity= 450/4= 112.5
Final velocity is 112.5- 15.5= 97
so, time taken is= 873/97= 9hours= 9*3600 secs= 32400secs.
Option 7.

Initial speed = 450/4 = 112.5 kmph
New speed = 112.5 - 15.5 =97 kmph
So time taken to travel 873 km with 97 kmph speed = 873/ 97 = 9hrs = 9*60*60 = 32400 seconds
