Two cars travel in the same direction at 40km/hr at a
regular distance. A car comes in the opposite direction at
60km/hr. It meets each car in a gap of 8 seconds. What is
the distance between the two cars?

Answer Posted / k10

speed = dist/time
two cars speed is 60+40=100km/hr(adding due to opposite direction)
should convert to m/s i.e 5/18
100*5/18=speed 
time =8sec
by formula
dist= speed*time
100*5/18*8=223m
ans is 223
