this is my classmates answer can you do me a simliar question and solve that question as my classmate did thank you 

1.A conductor in a train travelling at 4.0 m/s (N) walks across the train at 1.2 m/s (E) to validate a ticket. If the trian car is 4.0m wide, how long does it take the conductor to reach the other side? vog=? vom 1.2 m/s(E) (1.2/4.2) vmg= 4.0 m/s(N) vog=4.2m/s(N17E) Ad At = Δυ At = 3.3s 4.0m/s 1.2m/s vog=vom+vmg = 1.2m/s(E) + 4.0m/s(N) = sqrt (1.2m/s)^2 + (4.0m/s)^2 =4.2 m/s Tan-1= = 17
