Final answer:
The ratio of students in the van to students on the bus is 2:5. Using this information, we can determine the number of students in the van and on the bus. When 2 students move from the van to the bus, we can also calculate the new number of students in each vehicle.
Step-by-step explanation:
The ratio of students in the van to students on the bus going to the museum is 2:5. Let's assume that there are 2x students in the van and 5x students on the bus. We know that the total number of students is 56, so we can set up an equation: 2x + 5x = 56. Combining like terms, we get 7x = 56. Dividing both sides by 7, we find that x = 8.
Now we can determine the number of students in the van and on the bus. The number of students in the van is 2x = 2(8) = 16, and the number of students on the bus is 5x = 5(8) = 40.
When 2 students move from the van to the bus, the number of students on the bus becomes 40 + 2 = 42, and the number of students in the van becomes 16 - 2 = 14.
