The distance travelled or how far the car has travelled in 3.3 second at constant speed of 86.4 km/h is 79.2 m.
The speed of an object, also known as v in kinematics, is a scalar quantity that refers to the size of the change in that object's position over time. The average speed of an object over a period of time is calculated by dividing its distance traveled by the length of the interval. Velocity and speed are different concepts. Distance divided by time is the dimension of speed. The meter per second (m/s) is the metric unit used to measure speed.
Speed of car= 86.4 km/h
Since time is given in seconds, converting to km/h to m/s. For converting km/h to m/s, dividing the value given in km/h by 3.6
86.4 km/h= 86.4/3.6 m/s
= 24 m/s
Distance travelled= Velocity* Time
= 24 * 3.3
= 79.2 m
