- Two, trains, one from Howrah to Patna and the other from Patna to Howrah, start simultaneously.
Question 1:
Two, trains, one from Howrah to Patna and the other from Patna to Howrah, start simultaneously. After they meet, the trains reach their destinations after 9 hours and 16 hours respectively.The ratio of their speeds is:
A. 16 : 9
B. 4 : 3
Feedback Let us name the trains as A and B. Then,
(A's speed) : (B's speed) = √b : √a = √16 : √9 = 4 : 3.
(A's speed) : (B's speed) = √b : √a = √16 : √9 = 4 : 3.
C. 4 : 6
D. 9 : 16
