Answer 1

Answer:

3 PM , 5 PM , 11 PM

Step-by-step explanation:

From the graph it is evident that phone is getting charged from

1) t ( 8 ) - t ( 10 ) = 2 PM to 4 PM

(Note:-  t0 = 6AM, so t (8) = 6AM + 8 hrs = 2PM. Similarly t (10) = 4 PM)

2) t ( 10 ) - t ( 12) - 4 PM to 6 PM - Here is using the phone and charging so battery is flat

2) t ( 16 ) - t ( 18 ) = 10 PM to 12 Mid-Night

So answers are :-

3 PM , 5 PM , 11 PM
