Answer 1

@amistre64 @sami-21 @ghazi @Callisto Please help

Answer 2

well by changing hands, what do you mean, does it mean, interchanging position of hour and minute hand?

Answer 3

I also don't know what does the book mean by it but I do have the answer. Ok! Let us take the meaning as specified by you @ghazi ... what answer you arrived ?

Answer 4

well i consider as interchanging of minute and hour hands , which means both will acquire new position if turned by 180 degrees , lets say its 6 o clock then minute hand is at 12 and hour is at 6 and if hands are interchanged then it will be 12.30 , thats what i concluded

Answer 5

not 12.30 but a bit less, or lets say its 5 past 7 then if hands are interchanged , it will be 1.35 , thats what i can think of , but i guess here book says about mirror image like 5.25 and its mirror image is 6.40 , which satisfies your question

Answer 6

No but that is not the answer...

Answer 7

I think the question is wrong,,,,,

Answer 8

changing hands is confusing me , i think its 5.30 and then 6.25

Answer 9

like her left at 5.30 and if hands are changed it will be 6.25

Answer 10

*he

Answer 11

yes, clocks used to have hands on them to tell the time with :)

Answer 12

unfortunately its obsolete and now digital watch is preferred lol for higher precision and accuracy

Answer 13

so i guess i was correct lol

Answer 14

5.30 to 6.30 is a suitable result

Answer 15

but then we are talking about angles .... and not time itself lol

Answer 16

Well I don't think tht question means for mirror images..

Answer 17

exactly, i am trying to think of mathematical explanation and @mathslover we didnt use mirror image , we just interchanged the position of hands in your given time interval, 5 at 6 and 6 at 5 ;)

Answer 18

we have different angular speeds to acowingspan for
