Praxis 5003 Practice Test Practice Question
The distance of a train from a station, in kilometers, at three times is shown in the table. If the speed of the train is constant, what is the speed in kilometers per minute?
Correct Answer: 2.5 kilometers per minute
Rationale: To find the speed of the train, we need to calculate the total distance traveled and the total time taken. If the train covers a distance of 15 kilometers in 6 minutes, the speed is determined by dividing the distance by the time: 15 km / 6 min = 2.5 km/min.
Other options are incorrect as follows:
- 1.5 km/min underestimates the speed, suggesting a longer travel time without accounting for the actual distance.
- 3 km/min overestimates the speed, implying the train covers more distance in the same time frame.
- 5 km/min significantly exaggerates the speed, indicating an unrealistic travel capability based on the given distance and time.
