Answer:
There are total 25 trains.
Step-by-step explanation:
Given,
The number of exhibits = 5,
The number of train in each exhibit = 5, ( 1 track is for 1 train ),
Thus, the total number of trains( say n ) = number of exhibits × trains in each exhibit
[tex]\implies n = 5\times 5[/tex]
[tex]\implies n = 25[/tex]
i.e. there are total 25 trains.
