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.
What was the average time the car with the soft wheels took to cross the 75-foot mark?
选项
A、22.8 seconds
B、33.9 seconds
C、39.8 seconds
D、56.7 seconds
E、170.1 seconds
答案
D
解析
The correct answer is D. The soft wheels data is in the second table. Calculate the average of those three times:(57.0 + 56.4 + 56.7)+ 3 = 56.7
