Explanation:
From the given information:
Let assume that Percival catches Sir Rodney's horse in time "t" after covering a certain distance "s"
Then, using the second equation of motion:
FOR Percival, we have:
FOR Sir Rodney;
Equating both equations together; we have:
0.3t² = 3t
0.3t² - 3t = 0
0.3t(t - 10) = 0
If Percival's position at rest = 0
Then; t = 10 s.
