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
[tex]\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[/tex]
