Answer:
a). 18 minutes
b). 8.4 miles
Step-by-step explanation:
a). Let Luis meet Kristina after the time = h hours
So the distance traveled by Luis in h hours = Speed × time
= 8×h
= 8h miles
If Kristin started after 45 minutes of
hours then the distance traveled by her
= Speed × time
=
miles
Since after h hours distances traveled by Luis and Kristin are same so,

28h - 8h = 
20h = 21
h = 1.05 hours
So the time taken by Kristin = (h - 0.75)
= 1.05 - 0.75
= 0.30 hours ≈ 18 minutes
b). Distance traveled by Luis before Kristin catches Luis = 8×1.05
= 8.4 miles
Answer:
x=2.65
Step-by-step explanation:
First, we need to figure out how much the length of the sides is changing between the equations. In this case it is changing by a factor of 2.5. Now we need to work backwards. First use this equation:

This is because whatever the length of the side with x is, will be 14/2.5. So divide both sides by 2.5:

Next, add 5 to both sides:

Then divide both sides by 4:

An example of a ratio is 8:1 and u shouldn't tempt people
2.8 mi
3.3mi
4.8+7(3)=8+21=29mi
5.yes, she hikes continuously so distance can be fractional parts of a mile
7.y=12x+120, y=12(5)+120=180
8.y=6.5x+10,6.5(10)+10=75
