Final answer:

Using the formula t = d/r, where t is time, d is distance, and r is rate, and substituting the given values of d = 545.79 m and r = 48.3 m/h, the time (t) is calculated to be approximately 11.3 hours.

Step-by-step explanation:

To find the time (t) it takes to cover a distance (d) at a certain rate (r), we use the formula t = d/r. Given the rate (r) as 48.3 meters per hour (m/h) and the distance (d) as 545.79 meters (m), we can calculate the time as follows:

  1. Substitute the given values into the formula:
  2. t = 545.79 m / 48.3 m/h
  3. Perform the division to find t.
  4. t = 11.3 hours (rounded to the nearest tenth).

Therefore, the correct answer is (a) 11.3 hours.
