Studentka2010 [4]

First, you need to convert 5 1/4 feet to inches. 5.25 x 12 = 63 inches. The ratio of the height of the model to the height of the actual statue in simplest form is 1/42. I don't know if this is correct but I hope this helps you in any way.

Answer:

65 people.

Step-by-step explanation:

We have to work backwards.

We end with 63 people, and at the stop we lost 19 people and gained 17.

$x - 19 + 17 = 63\\$ ; if x = # people at the beginning

$x - 19 + 17 = 63\\x - 2 = 63\\x = 65$

There were 65 people on the train to begin with.
