216 pass
engers
Explanation:Speed of the train = 70 miles per hour
Total capacity of the train = 400 passengers
Capacity of train filled = 54%
We need to find the number of people on the train. This will amount to 54% of the 400-passenger train.
[tex]\begin{gathered} Number\text{ of passenger on the train = }54\text{ \% }\times\text{ total capacity of train} \\ Number\text{ of passenger on the train = }\frac{54}{100}\times\text{ 400} \\ \\ Number\text{ of passenger on the train = 216} \end{gathered}[/tex]
