Hi everyone,

I have another riddle for you! This one is pretty easy and it’s based on the River Crossing riddle, but I hope you enjoy!

You’re working at a very famous museum in Nowhere-Land. Your job is to oversee the various artifacts being moved from exhibit to exhibit. Since these artifacts are very fragile, you use a machine called the Artifact-Transporter 3000. There’s one problem though: The Artifact-Transporter 3000 will transport any object no matter its weight, but the speed of transporting will change depending on the object to make sure it gets transported in one piece.

You’re now overseeing a shipment of four items: An ancient papyrus scroll written by an Egyptian king, An old jewelry box given to a Chinese princess, An unknown Roman Emperor’s tombstone, and a Renaissance inventor’s unfinished invention. These items vary in weight. The papyrus scroll will take 1 minute to transport, the jewelry box will take 2 minutes to transport, the tombstone will take 5 minutes to transport, and the invention will take 10 minutes to transport. Your job is to bring all of the items from Exhibit A to Exhibit B. Unfortunately, you have only 17 minutes to transport all of the items, and you only have 1 Artifact-Transporter 3000s which can transfer at the most one item, going at the speed of the slowest item. To make matters worse, to use the Artifact Transporter again, you’ll need to attach an artifact to make it work.

Can you find a way to transport all of the items in time with the restrictions? There are no tricks involved: no buying more transporters, no asking your (strict) boss for more time, and no faking illnesses!

RULES:

1. You can bring two items (artifacts) over at a time, going at the speed of the slowest item. For example, if you’re transporting the invention and the scroll, you’ll take 10 minutes. You’re allowed to bring one item at a time, however.
2. To use the Artifact Transporter, you’ll need to attach an artifact to bring it back. For example, if you just transported the jewelry box to Exhibit B and you need to get the invention to B as well, you’ll need to attach an artifact that’s at B to bring the transporter back to A.
3. You can bring items back from each Exhibit.
4. To win, all items must be at Exhibit B before time is up.

HINTS:

1. The slowest artifacts will move the least.
2. You will use all of your time.
3. The jewelry box will be the second-to-last move.

SOLUTION:

1. Bring the scroll and the jewelry box to B. (+2 minutes)
2. Bring the scroll to A. (+1 minute)
3. Bring the tombstone and the invention to B. (+10 minutes)
4. Bring the jewelry box to A. (+2 minutes)
5. Bring the scroll and the jewelry box to B. (+2 minutes)
6. Congrats!

Congrats! You were able to save your job and bring the artifacts over for one of the largest museum events of all time. Now, let’s see about that tropical beach vacation…
