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:
- Substitute the given values into the formula:
- t = 545.79 m / 48.3 m/h
- Perform the division to find t.
- t = 11.3 hours (rounded to the nearest tenth).
Therefore, the correct answer is (a) 11.3 hours.
