Train A is 75 m long & travels at a uniform speed of 54 km/hr. Train B is125m long & travels at a uniform speed of 36 km/hr in the direction opposite to that of Train A. If these trains are crossing at a double track stretch, what is the time taken for the two trains to fully clear each other ?
***
distance=125+75=200m
speed=54+36=90 km/hr
travel time=distance/speed
=200m/(90 km/hr)
AMP Parsing Error of [(200m/90km)*hr*(km/1000m)*(3600sec/hr)=8 sec]: Invalid function '/hr)=8sec': opening bracket expected at /home/ichudov/project_locations/algebra.com/templates/Algebra/Expression.pm line 70. .
time taken for the two trains to fully clear each other=8sec
