On slippery roads, stopping distances may be how much greater than on dry pavement?
-
A.
About 20 times greater
-
B.
Roughly 50 times greater
-
C.
2 to 10 times greater Correct
-
D.
Up to 1.5 times greater
The answer is "2 to 10 times greater"
The Driving in Bad Weather section gives a wide range (2 to 10 times greater) rather than a single multiplier because the difference depends on how slick the road is. The wrong answers bracket the correct range with an underestimate, a modest overshoot, and a wild overshoot to catch guessers on either side.
The traps in the wrong answers
A. About 20 times greater
Overshoots the 10-times upper bound the manual gives for slippery-road stopping distance. This answer reaches for a big round number that matches winter-driving dread, drawing on impressions of icy roads rather than the specific figure given.
B. Roughly 50 times greater
Far exceeds the 2-to-10-times range the manual specifies. This answer picks the most alarming figure on the guess that ice-and-snow warnings must dwarf any modest multiplier.
D. Up to 1.5 times greater
Understates the effect the manual describes; the upper bound is 10 times, not 1.5. This answer reasons from everyday wet-road driving, where the difference feels like a small buffer rather than a many-fold jump.
