Answer:
you both will reach the home at the same time.
I) You can catch your sister.
ii) Reason: you both will reach home at the same time.
Step-by-step explanation:
Let "d" be distance from school to home.
Let's find the speed of you and your sister.
Speed =
Your speed =
Your sister's speed =
Today, You stayed for some extra help by the time your sister covered of the way home.
Remaining distance to reach the home =
=
Now let's find the time to be taken your sister to reach the home.
Time =
=
So, your sister will take 20 minutes to get home by the time your start.
We know that it takes you 20 minutes to reach your home.
Therefore, you both will reach the home at the same time.
I) You can catch your sister.
ii) Reason: you both will reach home at the same time.
1. Line l; point P not on l.( Take a line I and mark point P outside it or on the line.So from point P there are infinite number of lines out of which only one line is parallel to line I. Suppose you are taking point P on line I, from that point P also infinite number of lines can be drawn but only one line will be coincident or parallel to line I.
2. Plane R is parallel to plane S; Plane T cuts planes R and S.(Imagine you are sitting inside a room ,consider two walls opposite to each other as two planes R and S and floor on which you are sitting as third plane T ,so R and S are parallel and plane T is cutting them so in this case their lines of intersect .But this is not possible in each and every case, suppose R and S planes are parallel to each other and Plane T cuts them like two faces of a building and third plane T is stairs or suppose it is in slanting position i.e not parallel to R and S so in this case also lines of intersection will be parallel.
3. △ABC with midpoints M and N.( As you know if we take a triangle ABC ,the mid points of sides AB and AC being M and N, so the line joining the mid point of two sides of a triangle is parallel to third side and is half of it.
4.Point B is between points A and C.( Take a line segment AC. Mark any point B anywhere on the line segment AC. Three possibilities arises
(i) AB > BC (ii) AB < BC (iii) AB = BC
Since A, B,C are collinear .So in each case
