first convert speed into m/s i.e for Anuj =5*(5/18)=25/18 m/s
Amit=8*(5/18)=40/18 m/s
To get the time at which they will meet at starting point is = LCM (T1,T2)
T1is the time to cover 400m by anuj= 400*18/25=288 sec
T2 is the time to cover 400m by Amit=400*18/40=180 sec

Now lcm of T1,T2 =1440 sec=24 minute

distance- 400m
400m= 4/10km
anuj= 4/10*5=4/50km/hr
amit=4/10*8=1/20km/hr
then l.cm(4/50,1/20)=l.cm(4,1)/h.c.f(50,20)= 4/10 ans

prasanna  (5 years ago)

TIME=DISTANCE/SPEED
=DISTANCE/RELATIVE SPEED
=400%(5*5/18-8*5/18)
=240MIN (INTO SECONDS)
= 8 SEC
