(A) 12 Kmph
(B) 16 Kmph
(C) 18 Kmph
(D) 24 Kmph
Correct Option is: D
Let the distance be x km
Travelling at 20 kmph, Kishore will reach point P at 4pm.
Travelling at 30 kmph, Kishore will reach point P at 12noon.
Therefore, time taken when travelling at 20km – time taken when travelling at 30 km =4hours
X/20-X/30=4
(3x-2x)/60=4
x/60=4
x=240
Time needed if travelled at 20 kmph =240/20=12hours Therefore, to reach at 2 pm, his travelling time must
be (12-2)=10 hours
Hence, required speed =240/10=24 kmph
