During which of the following was the average travel time of the car the slowest?
A. Study 1, Trial 2.
B. Study 2, Trial 2.
C. Study 3, Trial 2.
D. Study 3, Trial 3.

Study 1
The students first drove the cart on a smooth asphalt road. One student drove the cart as the other student started the stopwatch. The student stopped the stopwatch as the cart crossed the 500-foot mark. The students calculated the results of three separate trials and averaged the results (see Table 1).

Study 2
The students repeated the procedure used in Study 1, except the cart was driven on the fairway (very short, well-groomed grass). The results are shown in Table 2.

Study 3
The students repeated the procedure used in Study 1, except they drove the cart through the rough (thick, long grass). The results are shown in Table 3.
