Answer 2

Answer:

the true time is 02:54 pm

answer option(2) 2:54 pm

Step-by-step explanation:

given, both clocks were set the correct time at 12 pm on sunday

and clock1 gains 2 min in 24 hours

to find: actual time when clock1 indicates 3 pm on wednesday

time difference between 12 pm sunday and 3 pm wednesday = 75 hours

In 24 hour, clock1 gains 2 min

in 24 hour clock1 gains 120 seconds

Thus, Clock1 gains 15 seconds in 3 hours

So, clock 1 gained 6 minute 15 seconds in 75 hours

thus, the actual time when clock 1 shows 3 pm is 02:53:45 pm

= 02:54 pm

therefore, the true time is 02:54 pm

the true time is 02:54 pm

answer option(2) 2:54 pm
