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.
1品=需
The total number of water station in the marathon of 26.2 miles will be,
103-2 = 26.2
2 = 26.2 - 109
Therefore, 7 = 26.2 • 10 will represent the total
number of water stations.
