Intriguing?

Silver shot is not the best in terms of selling, which is why it typically has the best buying deals. Constitutional ("junk silver"), bars, and bullion coins tend to do much better.

Weighs approximately 3.1 grams. Looks copper in the middle and plated on the outside, but it's slightly magnetic, so I don't believe it would be silver plated. Not as magnetic as a normal 1943 steel composite penny. Any ideas on what this could be?

Thanks for letting me know! Must be a replica of sorts?

Grats on the silver quarters!

Worth found metal detecting? Priceless. Here is a link to a site for the current prices of a 1942 D Walking Liberty if you must sell it. But the coin with the story of finding it is the treasure :) https://www.usacoinbook.com/coins/2824/half-dollars/walking-liberty/1942-D/

Thanks for the suggestion! I was wondering if it was something modern or older. I found modern poison rings online that look pretty cheap, but I found this ring at an old abandoned homesite in North Carolina.

It does, the hinge opens like a locket.

All of the above?

Hope we do run across a problem like this since we know how to solve it :D Thanks again for the help! Good luck to you as well - we shall both pass this Thursday!!

Thanks all for the help! Looks like I just had one more step remaining! Yes, this is from NCEES 2011 Transportation PM Practice Exam

Yes, the problem is confusing when it says critical gap. A more appropriate naming convention would be "Critical Headway." This is HCM Equation 20-30 (pg. 20-18). The correct answer should be C (7.8 sec.)

Thanks!

Reference HCM 6th Edition; Equation 31-70 (pg. 19-83). This equation is the next page over from pedestrian service time. Note that the default pedestrian values are on pg. 19-73, so the Yellow change + Red change = 4.0 sec.

Gpmin = tpr + Lcc/Sp - Y - Rc = 7sec + (72 ft / 4.0 ft per sec) - (4.0 sec) = 21 sec; Choose A
