Jayden ran the 400 meter dash in 55 seconds. How many seconds does it take him to run one meter?

To find out how many seconds it takes Jayden to run one meter, you can divide the total time by the total distance:

\[
\text{Time per meter} = \frac{\text{Total time}}{\text{Total distance}} = \frac{55 \text{ seconds}}{400 \text{ meters}}
\]

Calculating that gives:

\[
\text{Time per meter} = \frac{55}{400} = 0.1375 \text{ seconds}
\]

So, the correct answer is:

**C. 0.1375 seconds**
