This distance time graph represents a journey made by Sue. Work out how much time Sue spends travelling and how much time she spends stationary.

If, this doesn't make sense then see picture attached.

Please help me

stationary time is 2 hours 30 minutes

Traveling time is 3 hours 30 minutes

Step-by-step explanation:

There are two distinct line types on the graph

the horizontal ones and the ones going towards the upper part

The horizontal ones represent the stationary positions while the climbing one represent the traveling time

The horizontal ones are;

3 to 3:30

4-5

6:30 to 7:30

Time here is ;

30

minutes + 1 hour + 1 hour = 2 hours 30 minutes

The traveling time;

2 - 3

3:30 to 4

5 to 6:30

7:30 to 8

1 + 30 min + 1hr 30 + 30

= 3 hours 30 minutes

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
