A car travels a distance of 100 miles in a time of 2.6 hours. What is its average speed rounded to 1dp?

average speed = 260 km p/ h

Step-by-step explanation:

speed = distance × time

speed = 100 × 2.6  = 260

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

1. minimum

2. 6400

3. eight

hope this !
