The foot brake in your vehicle must be strong enough to stop the car traveling at 20 mph within how many feet?
-
A.
20 feet
-
B.
55 feet
-
C.
30 feet Correct
-
D.
75 feet
The answer is "30 feet"
The foot brake must stop a vehicle traveling at 20 mph within 30 feet. A learner who picks 55 feet is applying the emergency-brake stopping distance stated in the very next sentence to the foot-brake requirement.
The traps in the wrong answers
A. 20 feet
Reuses the speed figure as if it were the stopping distance. This answer reads the 20 mph speed in the same sentence as if it also set the stopping distance.
B. 55 feet
Applies the emergency-brake stopping distance to the foot-brake rule. This answer confuses the 55-foot emergency-brake distance with the foot-brake requirement in the sentence beside it.
D. 75 feet
Guesses a longer stopping distance no equipment rule sets. This answer overshoots both stopping figures, perhaps from a rough sense of highway braking distance.
