Explanation:
The distance travelled by the object during the first 4 seconds is 80 m
<h3>Definition of speed </h3>Speed is defined as the distance travelled per unit time. Mathematically, it can be expressed as:
Speed = distance / time
With the above formula, we can obtain the distance travelled by the object in the first 4 seconds.
<h3>How to determine the distance travelled </h3>- Speed = 20 m/s
- Time = 4 s
- Distance =?
Speed = distance / time
20 = distance / 4
Cross multiply
Distance = 20 × 4
Distance = 80 m
