Two bikes start simultaneously toward each other from two points 300 km apart. Meeting 130 km from one starting point, what is the ratio of their speeds?
Show answer Hide answer
Answer: A. 17:13
Explanation
Simultaneous starting times mean both bikes travel for the exact same duration until meeting. The ratio of speeds for objects traveling equal times equals the ratio of the distances covered. Dividing one hundred thirty kilometers by the remaining distance gives the correct comparative ratio. Kinematic equations link distance, speed, and time through direct proportional relationships. When travel time is constant, speed is directly proportional to the distance traveled. Ratio notation compares two quantities sharing the same unit of measurement.
Traffic management and collision avoidance systems calculate relative vehicle speeds continuously. Physics kinematics problems rely on distance and time ratios to analyze moving object dynamics. Transportation logistics uses speed comparisons to optimize fleet travel times between destinations. Option B suggests seventeen to thirty which compares a travel segment to the total distance. Option C proposes thirteen to thirty which also compares a segment to the total route length. Option D offers none of these, but option A provides the standard ratio context notation.
