Answer:
it's E) 5 hours 42 minutes
Step-by-step explanation:
the questions a gud one tbh, it's a 24 hour format clock, so if we add 4 hours the cloocl will be 00.20, but our goal is 02.02 ( upside down of 20.20) so we add 42 minutes so that 20+ 42 which equals 62, that is 1 hr 2 minutes so now we have 01.02 so we add an other hour so 5 hr and 42 minutes.
im really bad at explanations but I hope you understand
