Answer:
9.03 metres
Explanation: Given that an automobile is traveling at 60 ft/s (about 40 mi/h or 65 km/h). If the reaction time is 0.5 s.
From the question above,
Speed = 65 km/m
Time = 0.5 s. Convert the second to hour.
0.5 / 3600
Speed = distance/time
65 = distance ÷ 0.5 /3600
65 = distance × 3600 /0.5
65 = 7200 × distance
Distance = 65/7200
Distance = 9.03 × 10^-3 Km
Convert the distance to metre by multiplying it by 1000
Distance = 9.03 × 10^-3 × 1000
Distance = 9.03 m
