You need to come up with a way to time exactly 45 minutes how do you do it? if you have 2 wicks.?.?

light both ends of one wick and one end of the other.. after 30 min the first wick will burn out and the second wick will have 30 min remaining, once the first one burns out light the only remaining unlit end and that remaining half of wick will burn out in 15 minutes.. leaving you with nothing 45 minutes later. smart way to spend time if you ask me

so Joe is taking 20 hrs and Fred is taking 32 hours. If these two are to be given work, then 20/52% should be given to Fred and 32/52% should be given to Joe to get things done in time ( I mean both finishes at the same time)\n\nSo Joe's portion of work would be 64% and Fred wil do 36% work...\n\nsimple !

It's actually plenty of time. Count with the clock for like three minutes. Yipe! it's longer than you think. When you're in pain, 60 seconds is an eternity. It's plenty of time. Unless you're a bomb technician :0)

I used to get tripped up with these too!\n\nSo, it's all about speed, distance, time (s = d/t) and finding the 2 things you know, and getting an equation for the third unknown and solving it. Here, the speeds are given, and the difference in times are given.\n\nSay d is the distance Matt has to go, and t1 & t2 are the times he took to get there the first and second time.\n\nt1 = d/75\nt2 = d/45\n\nalso, he arrived one hour early the first time, and one hour late the second ==> the difference between these two times is 2 hours.\n\nt2 - t1 = 2\n=> d/45 - d/75 = 2\n=> (75-45)d/45*75 = 2\n=> d = 2*45*75/30\n=> d = 225 miles.

30 minutes is the recommended time. Longer is good. It is for fitness and improves health. It also is good in a lot of other ways. Read the links.

You could solve this by figuring out the rate the hour hand turns and the minute hand turns, etc.  But it is much easier to think laterally.\n\nThe hour and minute hands of a clock line up perfectly at 12 noon, then again at regular intervals after that.  But those intervals are not an even hour.  It's a little more.\n\nBecause the hands line up *eleven* times in a 12 hour period, the interval between alignment is 12/11.\n\nIf you convert this to a time, it is exactly:\n12/11 = 1.0909... hours\n= 1 hour 5.4545... minutes\n= 1 hour 5 minutes 27.2727 seconds\n= 1 hour 5 minutes 27 3/11 seconds.\n\nSo the time when the hour and minute hands align perfectly will be at: 1:05:27 3/11\n\nFirst alignment: 1:05:27 3/11\nSecond alignment: 2:10:54 6/11\nThird alignment: 3:16:21 9/11\n...\nTenth alignment: 10:54:32 8/11\nEleventh alignment: 12:00:00\n\nThe time between one and two o'clock is:\n1 hour 5 minutes 27 3/11 seconds.

30-40 min!!!!!!!!!!!!!1\nwho can do it??\nno ideal time but if you can ejaculation together this is the best way to injoy eatch other

so... i think you have to do this: first you light one thread at both ends (let's call this thread 1), and the other (thread 2) only at one end. When thread 1 burns completely you have measured 30 min, so you light the other end of thread 2. When thread 2 is burnt you know 45 min have passed since you started this process...

40 - two 20 min. halves

It depends on how fast you run/walk.  If you are doing a combo of running and walking, you can probably finish in 45 minutes or less.

None, just go slower and stop for 5 second breather now and then. Trust me, he'll be pissed but "IT" wont come out as fast.

Ok this still gets me sometimes but the easiest way for me to do it is to add 12 to the time then stick on 00 on the end \n\nfor example.  2pm\nyou add 12 = 14\nadd 00 = 1400\n\nthe am hours you dont do anything to it, well you dont add 12.  \n\nso 1pm would be 1300\n2pm=1400\n3pm=1500\n4pm=1600\n5pm=1700\n6pm=1800\n7pm=1900\n8pm=2000\n9pm2100\n10pm=2200\n11pm=2300\nmidnight=2400

look there's a 1&#92;6 because there are 2 hours(120 minutes)\n20 minutes is just 1&#92;6 of 120 minutes. is simple
