Andrew fitted an electric toy car with hard rubber wheels that had deep treads and placed the car on a smooth, flat surface. Andrew started the car and a stopwatch at the same time. Andrew stopped the stopwatch as the car crossed the 75-foot mark. He calculated the results of 3 separate trials as shown in the table below.
Andrew repeated the procedure, except he fitted the car with soft rubber wheels that were smooth and lacked treads. The results are shown in the table below.
[br] During which procedure and trial did the car travel at the highest speed?
选项
A、Procedure 1, Trial 1
B、Procedure 1, Trial 2
C、Procedure 1, Trial 3
D、Procedure 2, Trial 1
E、Procedure 2, Trial 3
答案
C
解析
The correct answer is C. The data in the tables reflects the amount of time the cars took to travel a constant distance. Therefore, the car that finished in the least amount of time traveled at the highest speed.
