Eggs Anyone?
Suppose you have only two egg timers, a five-minute and a three-minute. Can you use these two measuring devices to time an egg that must be boiled for exactly two minutes?
dear mr. b you could use the three min one and then you would set it for two min so then it would be able to work unless the timer could only do three and five you would have to go get a different timer
yes because one timer is 3 minnutes and the other is 5 minnutes so if you add those two numbers you will get 8 minnutes so you can use the two measuring devises to time the egg for 2 minnutes exact.
yes because you could use only use the three minute one
ReplyDeleteno you can't if you use both timers and only that amount of time on the timer.
ReplyDeletelook at the timers when when there is only 3 min. on the 5 min. timer. then only 1 min.left on the 3 min. timer.
ReplyDeleteNo you cant because if you use both egg timers that will equal 8 minutes and you only need 2 minutes.So the egg will boil for to long.
ReplyDeletei think it is cofusing but i think it is posible beacuse the timmer goes to 5 mins and 3 mins and two is lower than both of those so it works.:)
ReplyDeleteyes because you can set one to 2 min.

DeleteI agree
You have to set it to 3 and 5 it cant be lower than those.
Deleteno becase if you have two egg timers one set foe 5 minnuts and you have one for 3 and they need to be done at two minnuts
ReplyDeleteyes because if you set it to two min and you set it also on 5 mins you can just wach the clock to see when it is 2 mins
ReplyDeleteyes you can because if you set them at the same time when the 3 min. timer is up the egg is done
ReplyDeletedear mr. b you could use the three min one
ReplyDeleteand then you would set it for two min so then it would be able to work unless the timer could only do three and five you would have to go get
a different timer
I guess in a way that you could you start them at the same time but dont put the egg in untill the three min one is done.
ReplyDeletei agree RF7rm304
DeleteExactly!
Deleteyes because,you can tell them if they both if they get the same!
ReplyDeletetake the 3min timer wait till it says1min left and take the eggs out
ReplyDeleteyes because one timer is 3 minnutes and the other is 5 minnutes so if you add those two numbers you will get 8 minnutes so you can use the two measuring devises to time the egg for 2 minnutes exact.
ReplyDeleteOr you could (because they are egg clocks) crack the toghether and try to get 2.
ReplyDeleteYes.
ReplyDeleteBecause you can use the 3 minute timer.
Then watch it for two minutes, leaving a minute remaining
i think the answer is 1
ReplyDeleteyou do 5-3=2 thats what i think
ReplyDeleteBoth, but you subtract 5:00 min.
ReplyDelete-3:00 min.
=2:00 minutes
start them at the same time than put the egg in when the 3 minute one is done. It's 5:00-3:00
