Rinkal left her home at 5:00 PM and it took her 25 minutes to reach to the park from her home.
So she reached the park at 5:25 PM. [1 Mark]
If we add the time duration for the activities she did in the park, we get, 5+10+10 = 25 minutes. [1 Mark]
so, 25 minutes will be added to 5:25 PM, giving the time as 5:50 PM. [1 Mark]
So, Rinkal will leave the park at 5:50 PM. [1 Mark]
