D = 40
Was Jon faster?
S1
d1 = 10 at 30km/h
d2 = 30 at 15km/h
Avg speed = 75/4 = ~19km/h
But we don't know the avg speed for Ann and don't know if Jon took a break after 10kms
Insufficient
S2
Ann's speed = 20km/h
But we don't know the avg speed for Jon
Insufficient
Together:
Speed of Ann is greater. Ans it doesn't matter if Jon took a break. He will be slower regardless

Let’s determine if Jon completed a 40-km journey in less time than Ann by evaluating the statements.
We need to compare \(T_{Jon} < T_{Ann}\) for the 40-km journey.
Combining both statements gives us the times for Jon and Ann, allowing us to compare.
Answer: C
We need to compare \(T_{Jon} < T_{Ann}\) for the 40-km journey.
| Statement | Information Provided | Sufficiency |
| Statement 1 | Jon: 10 km at 30 km/h, then 30 km at 15 km/h. Time = \(\frac{10}{30} + \frac{30}{15} = \frac{1}{3} + 2 = \frac{7}{3}\) hours. No info on Ann. | Insufficient to compare. |
| Statement 2 | Ann: 40 km at 20 km/h. Time = \(\frac{40}{20} = 2\) hours. No info on Jon. | Insufficient to compare. |
| Statements 1 + 2 | Jon: \(\frac{7}{3} \approx 2.333\) hours. Ann: \(2\) hours. | Sufficient to compare. |
Combining both statements gives us the times for Jon and Ann, allowing us to compare.
Answer: C
