### 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?
﻿

1. yes because you could use only use the three minute one

2. no you can't if you use both timers and only that amount of time on the timer.

3. look 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.

4. No 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.

5. i 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.:)

6. yes because you can set one to 2 min.

1. vm17rm304

I agree

2. You have to set it to 3 and 5 it cant be lower than those.

7. no 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

8. yes 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

9. yes you can because if you set them at the same time when the 3 min. timer is up the egg is done

10. 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

11. 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.

12. yes because,you can tell them if they both if they get the same!

13. take the 3min timer wait till it says1min left and take the eggs out

14. 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.

15. Or you could (because they are egg clocks) crack the toghether and try to get 2.

16. Yes.
Because you can use the 3 minute timer.
Then watch it for two minutes, leaving a minute remaining

17. i think the answer is 1

18. you do 5-3=2 thats what i think

19. Both, but you subtract 5:00 min.
-3:00 min.
=2:00 minutes

20. start them at the same time than put the egg in when the 3 minute one is done. It's 5:00-3:00
