If a certain machine produces bolts at a constant rate, how many seconds will it take the machine to produce 300 bolts?
(1) It takes the machine 56 seconds to produce 40 bolts.
(2) It takes the machine 1.4 seconds to produce 1 bolt.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.

1) Gives rate for bolts per second. If one wants to solve: 56/40 = 28/20 = 14/10= 1.4 bolts per second. (Sufficient)

2) Gives bolts per second. 1.4 also equals 56/40 (Sufficient)

I don't know what to say, really. Three minutes to the biggest battle of our professional lives. You find out life's this game of inches, so is football. Because in either game - life or football - the margin for error is so small. I mean, one half a step too late or too early and you don't quite make it. One half second too slow, too fast and you don't quite catch it. I'll tell you this, in any fight it's the guy whose willing to die whose gonna win that inch. That's football guys, that's all it is. Now, what are you gonna do?
