let distance of train A=x km/h
and " " " B=( x+1)
if , they meet at same time then,
distance of train A=40km/h
and. " " B=60km/h
if distance is is more 120 then,
sol.
60x=40x+120
60x-40x= 120
20x =120
x =120/20
x=6km/h
distance of train A (x) =6km/h
" " " B = X+1
= 6+1 =7
and " " " B=( x+1)
if , they meet at same time then,
distance of train A=40km/h
and. " " B=60km/h

60x=40x+120
