Answer:2 km

Explanation:

Based on the facts provided, her evening walk is two and a half times. Her evening walk will thus cover (2.5 * m) kilometres.

Sierra takes her dog for two daily walks 7 days a week.

By adding the distances of the morning and evening walks for each day, one may determine the total distance travelled in a week:

The total distance equals the sum of your morning and evening walks times the number of days.

With the provided numbers replaced, we get: 49 = (m + 2.5m) * 7 here we assumed m as 1m

Simply put, 49 = 3.5m * 7

49 = 24.5m.

Divide both sides of the equation by 24.5 to find the value of m: m = 49 / 24.5 m = 2

Therefore, the morning walk is 2 kilometres long.
