Question

Train A traveling at a speed of 30 km/hr overtakes
train B in 72 seconds. If train B travels in the opposite
direction it takes just 24 seconds for train A to cross
train B. Find the speed of train B, if the trains are of
equal length. (in kmph)
​

Answer 1

Answer:

speed=distance/time

let both train length x total= 2x

train a =30*15/18=2x/72sec

x value= 300

convert 30k/hr= 30*5/18 m/

sec

train b speed= 600/24= 25k/hr
