Answer:
t = 5 seconds
Step-by-step explanation:
We have,
Speed of the truck, v = 4 m/s
It is required to find the time taken by a truck to travel 20 meters. It can be assumed that the time is t. Using the formula of speed.
[tex]v=\dfrac{d}{t}[/tex]
After rearranging, we get :
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{20\ m}{4\ m/s}\\\\t=5\ s[/tex]
So, the time taken by a truck to travel 20 meters is 5 seconds.
