Respuesta :

each run is 3 miles long

Answer:

3 miles.

Step-by-step explanation:

We have been given that in an 18-mile duathlon you run then Bike 12 miles and then run again.

The distance covered by running would be 18 miles minus 12 miles.

[tex]\text{The distance covered by running}=18\text{ miles}-12\text{ miles}[/tex]

[tex]\text{The distance covered by running}=6\text{ miles}[/tex]

Since two runs are the same distance, so distance of each run would be 6 divided by 2.

[tex]\text{The distance of each run}=\frac{6\text{ miles}}{2}[/tex]

[tex]\text{The distance of each run}=3\text{ miles}[/tex]

Therefore, the distance of each run was 3 miles.
