Given:
Distance between Lily and Wilder = 810 miles
They drive towards each other with Lily driving at 55 mph and Wilder driving at 80 mph.
To find:
After how many hours will they meet?
Solution:
Lily driving at 55 mph and Wilder driving at 80 mph towards each other. So, the relative speed is:
Relative speed 

We know that,



Therefore, Lily and Wilder will meet after 6 hours.
Answer:
Since this is a proportional relationship,
We know that the number which are proportional are a multiple of each other
the number which we can multiply one of the numbers to get the other number is the constant of proportionality
we could check for proportionality by using the following formula:
p1 / s1 = p2/s2 = p3/s3 = p4/s4 if they were equal, we can say that the relation is proportional
The value of any of the above values, p1/s1 , p2/s2 , p3/s3 , p4/s4 is the constant of proportionality
Therefore, the constant of proportionality = 20 / 5 = 4
/5:5,66;6;6(7(77:&:&3&3&4&4&;&&;;))&;
So just divide 100 by 25 which equals 4 then divide 120 by 30 which also equals to 4 and if the rest equal 4 then its proportional (1)
And then same for 2 and 3 just divided the bottom by the top and if they all get the same answer they are proportion and if one is not the same then it’s not
For the grids if the dots are line diagonally straight and it starts at the 0 then it’s proportional if not then it’s not
Hope this helps :)
A is the intercepted arc of the angle that measures 45 degrees. The rule here is that arc measures twice what the angle measures. If the angle measures 45 degrees, then the arc measures 45 * 2 which is 90 degrees. There has to be another choice there that is cut off. These are inscribed angles, and those are the rules for inscribed angles.
