➻Speed of train A is 20m/s
➻Speed of train B is 90km/h
➻We need to convert the quantity to m/s.
➻In order to perform such conversation, the given value must be multiplied by the fraction
➻Distance between two trains is 200m
➻The time in which they collide=?
➻Now, substituting in the formula,
➻The time in which the two trains collide is "4.5 Seconds" respectively.
