   Marking scheme

   A. $10:15$ — $06:50$ plus $3$ h is $09:50$, then $50+25=75$ min, which is $1$ h $15$ min, giving $10:15$. B adds the minutes without carrying the extra hour.

   D. $3$ h $35$ min — convert to the 24-hour clock: $2:20$ p.m. is $14:20$. From $10:45$ to $14:20$ is $3$ h $35$ min; going to $13:45$ first and then adding $35$ min confirms it.
