Is at - bs > 0?
1)
Substitute: \(t = 30 + s\)
Is a\((30+s) - bs > 0\) ?
Is \(30a + as - bs > 0\) ?
Is \(30a + s(a-b) > 0\) ?
Reference "distance" not "displacement: \(a, b, s, and t > 0\)
Rephrase: "Is \(a - b > 0\) ?" or "Is \(a - b\) positive ?" or "Is \(a > b\) ?"
Not Sufficient
1)
Substitute: \(a= 30 + b\)
Is \((30 + b)t - bs > 0\) ?
Is \(30t + bt - bs > 0\) ?
Is \(30t + b(t - s) > 0\) ?
\(a, b, s, and t > 0\) using the same reasoning
Rephrase: "Is \(t - s > 0\) ?" or "Is \(t - s\) positive ?" or "Is \(t > s\) ?"
Not Sufficient
1+2) Each statement answers the rephrased question of the other, anyway you ask it.
- Is \(t - s > 0\) ? -> Is \((30 + s) - s > 0\) ? -> Is \(30 > 0\) ? Yes. Sufficient
- Is \(t > s\)? Well, t is 30 greater than s. Yes. Sufficient
- Is \(t - s\) positive ? Yes, same reasoning. Sufficient
- Is \(a - b > 0\) ? -> Is \((30 + b) - b > 0\) ? -> Is \(30 > 0\) ? Yes. Sufficient
- Is \(a > b\) ? Well, a is 30 greater than b. Yes. Sufficient
- Is \(a - b\) positive? Yes, same reasoning. Sufficient
