Question

two trains A and B each of length 100m are running on parallel tracks one over takes the other in 20 seconds and one crosses the other in 10 seconds calculate the velocities of each train

Answer 1

s=200m
200/(vB-vA)=20sec
vB-vA=10

200/(vB+vA)=10
vB+vA=20

therefore,
vB=15 m/s
vA=5 m/s

hope this helps
mark branliest if helped

Answer 2

__________v = 5 m/s___________
