Half marathon is 13.1 miles long. thursday what is station every 111/120 miles along the race trail. which expression represents the total number of water stations a(13.1-111/120) b(13.1+111/120) c(13.1(111/120)) d(13.1÷111/120)

Step-by-step explanation:

If every 111/120 miles is a station, and total miles long is 13.1, the procedure to calculate the total number of stations is:

111/120 = 0.925; which means that there's a station every 0.925 miles. This number must divide the total 13.1 miles, to know how many stations there are.

13.1/0.925=14.16.

Therefore, there are 14 water stations.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
