I hate math! So let's simplify this,
1x satchel charge x 20 chickens= 1 Family meal from Chicken Express.

Good job Lawman!

b) 20

2/3 of 15 miles equals 10 miles

15 / 3 = 5

5 * 2 = 10

40mph = 10 miles * time

10 miles / 40 mph = time

time = .25 hr

.25 hr * 60 = 15 minutes

60 mph = 1 mile per minute

5 minutes + 15 minutes = 20 minutes

If it goes anything like the DHS test I took for CBP, you'll walk out wondering why you were concerned.

I do sympathize however: when I had to relearn all the crap I haven't used since middle school, I was taken aback by how much I forgot.  DHS didn't let us use a calculator either.  I had to reacquaint myself with long division and algebra on paper.  I was watching youtube videos :'D like a 5th grader.  Kids these days have it easy what with all this interwebs and stuff.  And here I was thinking two decades ago 'This is dumb.  I'll always have a calculator somewhere near by...'.  Damn you Mrs. Black for being right!

You'll be fine! Its just like any other skill...if you don't use it, you'll lose it. I would recommend https://www.khanacademy.org/math (https://www.khanacademy.org/math) for a refresher. That site really helped me get through my differential equations course at University.
