Rahul and Neeraj start at the same time from points A and B and travel towards B and A respectively. After they meet, Rahul takes 40 minutes to reach B and Neeraj takes 1.5 hours to reach A. If Rahul's speed is 36 kmph, find Neeraj's speed.
A
54 kmph
B
30 kmph
C
24 kmph
D
48 kmph
Correct Option - C
Explaination
If two people P and Q start at the same time from points A and B towards each other and after crossing each other, they take x seconds and y seconds to reach B and A respectively,
P's speed:Q's speed = √y:√x
Rahul's speed:Neeraj's speed
= √(1.5*60):√40
= √9:√4
= 3:2
Neeraj's speed
= 36*2/3
= 24 kmph
