I Can Be Quick, And Then I’m Deadly

I can be quick and then I’m deadly,
I am a rock, shell and bone medley.
If I was made into a man, I’d make people dream,
I gather in millions by ocean, sea and stream.

Sand. Quicksand is deadly (at least in movies). Sand is made up of rocks, shells and bones. The sandman visits you when you dream (again, according to legend, I’ve never seen him…) and there is plenty of sand in the oceans, seas and streams.

Hear a Lot, Say a Lot

I hear a lot
And I say a lot
Few ever look for me
And even fewer ever hear me
I hide in plain sight
Whether its day or night
To help is all I want
But most like to bend me
And as if they had a wand
Never again shall anyone find me
They do this to control
Without realizing the high price of a soul
But when I’m least expected
They’d rather be protected
For there shall be no place to hide
What am I?

The truth.

Right Behind You Creeps on the Ground

It’s right behind you,
And creeps on the ground,
It follows you home,
But does not make a sound.
Careful when you turn around.

What is it?

Your shadow.

The Train and the Tunnel

A train is a half mile long and is about to enter a 10 mile tunnel. If the train is traveling at 35mph, how long will it take for the entire train to make it through the tunnel, from the front of the train entering to the end of the train leaving the tunnel?

18 minutes.

Length of the train: 0.5 miles
Length of the tunnel: 10 miles
Total distance: 0.5 + 10 = 10.5 miles

Time = 10.5 miles / 35 mph = 0.3 hours = 18 minutes
