Answer:
Distance = 70 meters
Explanation:
<u>Given the following data;</u>
Speed = 90 km/h
Time = 2.8 seconds
<u>Conversion:</u>
90 km/h to meters per seconds = 90 * 1000/3600 = 90000/3600 = 25 m/s
To find the distance covered during this inattentive period;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the formula;
Making distance the subject of formula, we have;
Substituting into the above formula, we have;
<em>Distance = 70 meters</em>
