How much time will it take for a truck to travel 20 meters if it is traveling at 4m/s

Mathematics

Zinaida [17]3 years ago
5 0

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.

v=\dfrac{d}{t}

After rearranging, we get :

t=\dfrac{d}{v}\\\\t=\dfrac{20\ m}{4\ m/s}\\\\t=5\ s

So, the time taken by a truck to travel 20 meters is 5 seconds.
