Chapter 6.2, Problem 16PPS

To determine

Express 400 meters in 58 seconds as a unit rate.

Answer to Problem 16PPS

  $6.9\frac{\text{meters}}{\text{seconds}}$

Explanation of Solution

Given:

400 meters in 58 seconds

Calculation:

Unit rate $=\frac{400\text{meters}}{58\text{seconds}}=\text{6}\text{.896}\frac{\text{meters}}{\text{seconds}}$

Now, rounding it to nearest tenth,

  $\text{6}\text{.896}\frac{\text{meters}}{\text{seconds}}=6.9\frac{\text{meters}}{\text{seconds}}$

Conclusion:

Therefore, the unit rate is $6.9\frac{\text{meters}}{\text{seconds}}.$
