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 go in depth and explain step by step im slow)

15 seconds

Step-by-step explanation:

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

Now  , of total length L is covered in time .

We know distance traveled =speed×time

Let Object's velocity be V

Using this

Thus, velocity in terms of total length is

Now,

 To cover total length L time needed is

Time taken =15 seconds

people went from manufacturing one object at a time by hand to manufacturing many objects in factories

b is the answer that makes most sense
