Question

An object travels along a horizontal straight path at a constant rate. The object travel 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?

Answer 1

Answer:

Step-by-step explanation:

15 seconds

Answer 2

Answer:

15 seconds

Step-by-step explanation:

we know that

The object travel 1/20 of the length of the path in 3/4 second

so

using proportion

Find out how many seconds does it take the object to travel the entire length of the path

Remember that

The fraction of the entire length of the path is 20/20 and this fraction is the same that 1

so

$\frac{(1/20)}{(3/4)}=\frac{1}{x}\\\\x=\frac{3}{4}:\frac{1}{20}\\\\x=\frac{20*3}{4*1}\\\\x=\frac{60}{4}\\\\x=15\ sec$
