How many seconds will it take to drive to San Francisco from Los Angeles if an average speed of 67.0 mi/hr is maintained

Approximately 20525 seconds

Step-by-step explanation:

Distance between San Francisco and Los Angeles is not given.

Therefore, by using I-5 S, distance between these cities = 381.6

                                                                                             ≈ 382 miles

Formula for the average speed is,

Average speed =

Time taken to reach San Francisco from Los Angeles =

                                                                                       =

                                                                                       = 5.702 hours

                                                                                       ≈ 5 hours 42 minutes

                                                                                       ≈ 342.1 minutes

                                                                                       ≈ 20525 seconds

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
