The motion of two car A and B is shown in the figure. Relative velocity of car A w.r.t. carb is vA B=vA-vB=15-10=5 m / s <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/b4a0649ad46e616b575790eb9db9657c-.png" /> Distance to be covered for overtake is given as s=4 m+4 m=8 m Time taken by cars to cross = DistanceVSpeed =(s/VA B)=(8/5)=1.6 s
