Amule deer can run one over four of a mile in 25 seconds. at this rate, which expression can be used to determine how fast a mule deer runs in miles per hour? a. twenty-five seconds over one-fourth mile = 36 miles per hour b. one-fourth mile over twenty-five seconds = 36 miles per hour c. one-fourth mile over twenty-five seconds = 100 miles per hour d. twenty-five seconds over one-fourth mile = 100 miles per hour

At this rate, which expression can be used to determine how fast a mule deer runs in miles per hour. A 25 seconds/ 1/4 mile = 36 miles per hour

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
