The table shows the race time for Jon, who competed in three different youth triathlons.

What is Jon’s total time for the June triathlon?

9 . 5
1 3 . 0
+ 2 3 . 7

Jon’s total time is minutes.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

well in order to answer the question, you have to give us the dimensions of the prism first.
