The movie will end at 8:48 PM.
The movie starts at 7:00 and runs for 108 minutes. To find the end time, we add the duration of the movie to the starting time. Since 108 minutes is equal to 1 hour and 48 minutes, the movie will end at 8:48 PM.

The number of ways the train could be made up are 4,151,347,200.
A permutation of a set is an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements.
Now the given cars are 6 flatcars, 7 boxcars, and 3 livestock cars.
So the total number of cars, n = 6 + 7 + 3
= 16
Now, a train is made up of 9 cars,
Therefore, r = 9
Hence the required number of ways the train could be made is nPr
nPr = n!/(n-r)!
nPr = 16!/(16-9)!
nPr = 16!/7!
nPr = 16*15*14*13*12*11*10*9*8
nPr = 4,151,347,200
Hence,the number of ways the train could be made up are 4,151,347,200.
