Rajesh went out between 5 and 6 for a work. He came to home between 6 and 7. When he came he saw that the hands have exactly changed places. When did Rajesh went out?

Best ResponseYou've already chosen the best response.2well by changing hands, what do you mean, does it mean, interchanging position of hour and minute hand?

Best ResponseYou've already chosen the best response.0I 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 ?

Best ResponseYou've already chosen the best response.2well 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

Best ResponseYou've already chosen the best response.2not 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

Best ResponseYou've already chosen the best response.2changing hands is confusing me , i think its 5.30 and then 6.25

Ghazi

Best ResponseYou've already chosen the best response.2like her left at 5.30 and if hands are changed it will be 6.25

Best ResponseYou've already chosen the best response.15.30 to 6.30 is a suitable result

Best ResponseYou've already chosen the best response.0Well I don't think tht question means for mirror images..

Ghazi

Best ResponseYou've already chosen the best response.2exactly, 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 ;)

Best ResponseYou've already chosen the best response.1the hour hand has a constant speed of 360 per hour; the minute hand has a speed of 360/60 per hour. if you can narrow down how to account for a general position you can use the speeds to find a related rates problem maybe .... or it could be one of the harry and sally paint a room things

Best ResponseYou've already chosen the best response.1we know the time had to be less than an hour, since the minute hand didnt make it all the way around ....

Best ResponseYou've already chosen the best response.1lets assume 50 minutes just to cover the span from the 5 to the 7 and my speeds are off

amistre64

Best ResponseYou've already chosen the best response.1minute hand is 360 per hour; and hour hand is 360+360/12

Best ResponseYou've already chosen the best response.2minute hand moves faster than hour, minute hand completes 360 degrees in one hour and hour hand covers only 30 degree in one hour

Best ResponseYou've already chosen the best response.1also need to determine the angle of separation at a given time .... im sure someones figured this out in like 1587bc

Best ResponseYou've already chosen the best response.1dw:1360762766659:dw for a given degree alpha we need to determine when "equivalent" distances get traveled at a given speed; when alpha = 360alpha does that make any sense?

amistre64

Best ResponseYou've already chosen the best response.1the time interval is the same for each distance traveled \[hour: \frac{30^o}{60sec}t=\alpha^o\\minute:\frac{360^o}{60sec}t=360^o\alpha\] 2 equations in 2 unknowns right?

Best ResponseYou've already chosen the best response.1\[\frac{390^o}{60}t=360^o\] \[t=60sec~\frac{360^o}{390^o}=55\frac{5}{13}sec\]

amistre64

Best ResponseYou've already chosen the best response.1\[\alpha=\frac{30^o}{60sec}*\frac{720}{13}sec=(\frac{360}{13})^o\] at what time between 5 and 6 are the hands that many degrees apart? id start at noon and do some additional calculations

Best ResponseYou've already chosen the best response.1dw:1360764111867:dw \[\frac{360^o}{60}t(150^o+\frac{30^o}{60}t)=(\frac{360}{13})^o\] solve for t

Best ResponseYou've already chosen the best response.1at any rate, i got a good idea, might have the speeds off tho so dbl chk if your interested in it:)
