In a situation where two buses, R and S, are moving in the same direction with bus S attempting to overtake bus R. Given that the gap between bus R and bus S is 144 meters and bus S fully exceeds bus R in 36 seconds, what's the speed of bus S?
Statement I: Bus R is 165 meters in front of bike A, which has a speed that is 11 m/s more than that of bus R, and bike A passes bus R in 15 seconds.
Statement II: Bus R is 450 meters ahead of bike B, bike B's speed is 2 m/s faster compared to bus S, and bike B overtakes bus R in 75 seconds time.
Statement III: Bus R's speed is 70% of bike B's speed, and bike B can cover the length of a 140-meter tunnel in 7 seconds.
1
Statement I alone is sufficient to answer the question.
2
Statement Il alone is sufficient to answer the question.
3
Statement III alone is sufficient to answer the question.
4
Only statements Il and III together are sufficient answer the question.
