In finding the minimum amount of time that Brandon can swim is to add the quotient of the distance to swim and its velocity and the quotient of the difference of 250 and the distance cover in running and its velocity. The minimum time is 43.33 seconds
For this case, the first thing we must do is define variables.
We have then:
x: number of cabins
y: number of campers
We now write the equation that models the problem:

We know that there are 148 campers.
Therefore, substituting y = 148 in the given equation we have:

From here, we clear the value of x:

Therefore, the number of full cabins is:

Answer:
The number of full cabins is:
