Question

How much time will it take for a spider crawling across the floor at.5 m/s to get 4 meters away?

Answer 1

The time it will take the spider to crawl across the floor is $0.8\text{ seconds}$

The formula relating the speed of the spider crawling across the floor, the distance it travels, and the time taken to cover that distance is

$\text{speed}=\dfrac{\text{distance}}{\text{time}}$

Given information

From the question, we are given the speed of the spider as $5m/s$, and the distance covered as $4m$. What we need to find is the time taken to cover a distance of $4m$ when crawling at a speed of $5m/s$.

Computation

Substituting the given values into the previous formula, we get

$\text{speed}=\dfrac{\text{distance}}{\text{time}}\\\\5=\dfrac{4}{\text{time}}\\\\\implies 5\times \text{time}=\dfrac{4}{\text{time}}\times \text{time}\\\\\implies 5\times \text{time}=4\\\\\implies \dfrac{5\times \text{time}}{5}=\dfrac{4}{5}\\\\\implies \text{time}=\dfrac{4}{5}=0.8\text{ seconds}$

The time it will take will be $0.8\text{ seconds}$
