Which answer would score higher? Not sure where to start? Explain this Answer A Speed multiplier = 27 ÷ 18 = 1.5, so the braking-distance multiplier = 1.5² = 2.25. The dry-road estimate is 32 × 2.25 = 72 m; ice gives 126 m, which is 54 m farther. A much larger gap is needed in icy conditions because the car travels farther while braking. Answer B Speed multiplier = 27 ÷ 18 = 1.5, so the braking-distance multiplier = 1.5. The dry-road estimate is 32 × 1.5 = 48 m; ice gives 126 m, which is 78 m farther. A much larger gap is needed in icy conditions because the car travels farther while braking.
