Question

An object travels along a horizontal straight path at a constant rate the object travels 1/20 of the length of the path in 3/4 second at that rate how many seconds does it take the object to travel the entire length of the path?
(if you answer please go in depth and explain step by step im slow)​

Answer 1

Answer:

15 seconds

Step-by-step explanation:

Simply assume that total length to be covered be 'L'.

Now  , $\frac{1}{20}$ of total length L is covered in time $\frac{3}{4}seconds$.

We know distance traveled =speed×time

Let Object's velocity be V

Using this

     $\frac{L}{20}=V×time$

    $\frac{L}{20}=V*\frac{3}{4}$

Thus, velocity in terms of total length is

      $V=\frac{L}{15}$

Now,

 To cover total length L time needed is

$time =\frac{distance}{speed}$

$time=\frac{L}{\frac{L}{15} }$

Time taken =15 seconds
