v =
Step-by-step explanation:
Let the trains A and B meet each other after t hours after the departure of a train A.
Distance traveled by train A in t hours = Speed × time
= 60 × t
Distance traveled by train B = v × t
Since, Distance between the cities A and B = 600 km
60t + vt = 600
vt = 600 - 60t
v =
Therefore, expression that the represents the relation between v and t will be,
v =
