A marathon is 26.2 miles long. There is a water station every 114 miles along the race route. How many water stations are needed for this marathon?

26.2 * 100/103

Ex: We are told that a  marathon is 26.2 miles long. There is a water station every 1 and 3/100 miles along the race route. We are supposed to write an expression that represents the total number of water stations.

Let x be total number of water stations.

First of all we will convert our mixed fraction into improper fraction.

The total number of water station in the marathon of 26.2 miles will be,

Therefore, 26.2 * 100/103  will represent the total number of water stations.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
