A car is moving at a rate of 72 km/ hr. How far
does the moves stop after 4 seconds

Answer 1

Distance = 80 meters

Step-by-step explanation:

Given the following data;

Speed = 72 km/hr

Time = 4 seconds

Conversion:

72 km/hr to meters per seconds = 72*1000/3600 = 72000/3600 = 20 m/s

To find the distance covered by the car;

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;

`Speed = (distance)/(time)`

Making distance the subject of formula, we have;

`Distance = speed * time`

Substituting into the above formula, we have;

`Distance = 20 * 4`

Distance = 80 meters
