250:25=10

Answer 2

Task Analysis

To solve the problem, we need to determine the number of large buses used for the excursion. Then, we will create and solve a similar problem to find the total number of buses used.

Number of Large Buses

To find the number of large buses used for the excursion, we can use the information provided about the number of students in each type of bus.

The number of students in small buses = 5 buses * 20 students/bus = 100 students The number of students in large buses = (199 total students) - (100 students in small buses) = 99 students

Now, we need to find out how many large buses are needed to accommodate 99 students.

Calculation

To find the number of large buses needed, we can use the information that each large bus can accommodate 33 students.

Number of large buses = 99 students / 33 students/bus = 3 large buses

Therefore, there were 3 large buses used for the excursion.

Similar Problem

Let's create a similar problem with the same condition and question.

New Problem

199 students went on an excursion. Some traveled in small buses, with 20 students in each bus, and the rest traveled in large buses, with 33 students in each bus. How many buses were used in total?

Total Number of Buses

To find the total number of buses used for the excursion, we can use the information provided about the number of students in each type of bus.

The number of students in small buses = 5 buses * 20 students/bus = 100 students The number of students in large buses = (199 total students) - (100 students in small buses) = 99 students

Now, we need to find out how many buses are needed to accommodate 99 students.

Calculation

To find the total number of buses needed, we can use the information that each small bus can accommodate 20 students and each large bus can accommodate 33 students.

Number of small buses = 100 students / 20 students/bus = 5 small buses Number of large buses = 99 students / 33 students/bus = 3 large buses

Total number of buses = 5 small buses + 3 large buses = 8 buses

Therefore, a total of 8 buses were used for the excursion.

I hope this helps! If you have any further questions, feel free to ask.
