Answer:

9 hr 11 min 5 sec

Step-by-step explanation:

$\huge\mathfrak\green{ \boxed{Answer: - }}$

a)

=> 1 hr = 60 min

=> 5 hr 45 min = 5 × 60 + 45 min

=> 345 min

=> 1 min = 60 sec

=> 345 min 35 sec = 345 × 60 + 35 sec

=> 20735 sec

=> 1 hr = 60 min

=> 3 hr 25 min = 3 × 60 + 25 min

=> 205 min

=> 1 min = 60 sec

=> 205 min 30 sec = 205 × 60 + 30 sec

=> 12330 sec

Now, add them and convert

→ 20735 sec + 12330 sec = 33065 sec

→ 1 min = 60 sec

→ 33065 sec = 33065 ÷ 60 min

→ 551 min 5 sec

→ 1 hr = 60 min

→ 551 min 5 sec = 551 ÷ 60 hr + 5 sec

→ 9 hr 11 min 5 sec
