Answer:
[tex]\frac{3}{2}=1\frac{1}{2} =1.5 m[/tex]
Step-by-step explanation:
Hi!
In this case we have to write a proportion. Let's use x to represent how long it will take the diver to dive to a depth of 5 kilometers.
So the proportion will look like this:
30m ~~ 9m
5m ~~ xm
This can be written as:
[tex]\frac{30}{5}=\frac{9}{x} \\6=\frac{9}{x} \\6x=9\\x=\frac{9}{6}\\ x=\frac{3}{2}[/tex]m
