B

Table with 6 columns and 2 rows.Row 1: Column 1, 'Time (min)'; Column 2, '5'; Column 3, '6'; Column 4, '7'; Column 5, '8'; Column 6, '9' Row 2: Column 1, 'Speed (mph)'; Column 2, '45'; Column 3, '45'; Column 4, '45'; Column 5, '43'; Column 6, '41'

C

Table with 6 columns and 2 rows.Row 1: Column 1, 'Time (min)'; Column 2, '5'; Column 3, '6'; Column 4, '7'; Column 5, '8'; Column 6, '9' Row 2: Column 1, 'Speed (mph)'; Column 2, '45'; Column 3, '43'; Column 4, '41'; Column 5, '42'; Column 6, '43'

D

Table with 6 columns and 2 rows.Row 1: Column 1, 'Time (min)'; Column 2, '5'; Column 3, '6'; Column 4, '7'; Column 5, '8'; Column 6, '9' Row 2: Column 1, 'Speed (mph)'; Column 2, '45'; Column 3, '43'; Column 4, '41'; Column 5, '41'; Column 6, '41'

Explanation

The speed must rise at first and then fall. In choice A, it increases from 45 mph to 47 mph to 49 mph, then decreases to 48 mph and 47 mph. The other tables either only decrease, decrease and then increase, or decrease and then stay constant.
