Jameson is following a 3- kilometer exercise route. after every 1/5 kilometer there is a sign describing an exercise to do, including at the end of the route. which expression can be used to find the number of exercise signs along the route?

The answers are:

A.  

and

C.

From the statement we know that there is a sign every 1/5 km, it means that there will be a total of 5 sign for each entire km.

Then, we can calculate how many signs along the route exists in two ways:

First way:

Dividing the route distance into the sign distribution:

Second way:

Calculating how many signs exists per one (1) Km and then, multiply it by 3:

From the statement we know that there is a sign every 1/5 km, so there will be 5 signs every 1 km.

Hence,

Using both ways we can conclude that there is a total of 15 signs along the route.

Have a nice day!

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
