Final answer:
To calculate the total number of passengers on a train, the ratio of seated to standing passengers is needed. Given that ratio and the known number of 288 seated passengers, one could determine the total passenger count.
Step-by-step explanation:
The student has asked about the total number of passengers on a train, given that there are 288 passengers seated. However, the ratio of the number of passengers who are seated to the number who are standing is not provided.
To give a precise answer, this missing information is needed. Assuming the ratio was provided elsewhere in the question or the previous parts of the homework, we could calculate the total number of passengers by using the following steps:
Determine the ratio of the number of passengers seated to the number of passengers standing.
Calculate the number of passengers standing based on the given ratio and the number of passengers seated (288).
Add the number of passengers standing to the number of passengers seated to find the total number of passengers on the train.
Without the specific ratio, we cannot complete the calculation to find out how many passengers there are altogether.
