After some consideration, I have to say, I'm not sure WHAT  the answer to this question might be.

For instance, in this case, if something were sped up by 50%....50% of 15 = 7.5 sec. So now, it should take only half as long. But, by the same token, if it was sped up by 100%, it wouldn't take any time at all, since 100% of 15 is 15.....!!!

I guess that I'm unsure if something can be sped up by 200%....???

Any constructive criticism is welcome, here...!!!

In light of this, maybe Melody's answer of 5 seconds represents about a 67% increase???....(since 67% of 15 = 10.....???)

D / R = T  .....so ...  18.4m / (35m/s) = about .526 sec

125/8 = 16 boxes

A) 33.52 is what percent of 8

Just divide (33.52 by 8) x 100%  = 419%

B) 76.8% of what is 40.32    76.8% = .768  ... and  "of" means multiply.. and we'll let "what" = N  ...so we have

.768 x N  = 40.32     divide both sides by ,768

N = 40.32 / .768 = 52.5 = N

We have the number of possible hands that include no queens or one queen.

For the number that include no queens, we want to select 5 cards from any of 12 ranks, not including the queens. So we have C(48,5) =1,712,304

For the number that include one queen, and no more, we want to choose 1 of the 4 queens and then any 4 cards from the other 48. So we have C(4,1)*C(48,4) = 778,320

And adding these together, we get,  2,490,624

10^1.36 = 22.9087

Notice that 8/13 of every ml is made of compond B

So.....(8/13) * 1014 = 624 ml

-----------------------------------

We an use a proportion here........

12/ 320 = x / 296    cross-multiply

12*296 = 320*x     divide both sides by 320

12*296/320 = x = 11.1 gallons

By the Pythagorean Theorem, we have

L = √[40^2 + 48^2] = √3904 = 62 inches (rounded)
