Answer:
a) 9.095 seconds
b) 8.2286 seconds
Step-by-step explanation:
a) The train and the person both move in same direction
So, relative speed= 100-5= 95kmph
time=distance/velocity
=240x3600/(95x1000)
=9.095 seconds
b) The train and the person both move in opposite direction
So, relative speed= 100+5= 105kmph
time=distance/velocity
=240x3600/(105x1000)
=8.2286 seconds
