Answer:
i cannot help you get the answer to the question without more information but i can explain how to solve it, what your question is, is called a "permutation"
Step-by-step explanation:
To calculate permutations, use the equation nPr, where n is the total number of choices and r is the amount of items being selected. To solve this equation, use the equation nPr = n! / (n - r)! , an exclimation point means the factorial, say we need the factorial of 4, we would do this 4x3x2x1 go left to right, and it is not all at once. you multiply 4 times 3 which equals 12, then multiply 12 times 2... so on and so forth
Answer:
250 miles
Step-by-step explanation:
The given distance between the house and the beach is 125 miles.
Let 
miles be the distance between the house and the lunch stop.
So, at the time of the lunch stop, he already traveled miles, the remaining distance is the distance between the lunch stop and the beach.
Let 
miles be the remaining distance, so
Give that the ratio of the distance he has traveled, , to the distance he still has to travel, , is 
,i.e
Hence, the distance traveled by Herman when he stops for lunch is 250 miles.
