A motorist travelling at 72kmh‾¹ had his eyes shut for 0.4s during a hard sneeze. Calculate the distance covered by him during this time interval.

A. 50.0m
B. 28.8m
C. 18.0m
D. 8.0m

Correct Answer: Option D

D. 8.0m

Explanation

Convert velocity from kmh‾¹ to ms‾¹, by multiplying 1000/3600,

72×1000/3600 = 20ms‾¹

Therefore, distance covered in 0.4s = 20×0.4=8m
