Reading the graph, you get 300 km in 4 hours.
Givens
Formula
v = d/t
Solution
v = 300/4 = 75 km/hour which is the slope.
Comment
Any point that you can read accurately will give you the same answer. Since the point are not that readable, you can estimate one of them
Try
t = 6 hours
d = 450 km An estimate. It looks to be 1/2 way between 400 and 500 km when t = 6 hours.
v = ??
v = 450/6
v = 75 miles / hour << Answer
1/R=1/3+1/6
1/R=2/6+1/6=3/6
R=6/3=2ohms
Total R=2ohms

Check attachment for better understanding
Explanation:
Given that
a= 0.75m
b=1.31m
c= 2.2m
Weight of pole is 26.90
Then, Fg = Weight = 26.90
Using Equilibrium of forces
ΣFy = 0
U — D — Fg = 0
U — D = Fg
U — D = 26.9
To calculate U,
We will take moment about point A.
ΣMa = 0
Let the clockwise moment be positive and anti-clockwise be negative
Fg(a+b) — U(a) = 0
26.9(1.31+0.75) —0.75U = 0
26.9(2.06) = 0.75U
0.75U = 55.414
U = 55.414/0.75
U = 73.89 N
To calculate D,
U — D = 26.9
73.89—D =26.9
73.89—26.9 = D
D = 46.99N
Answer:
1946 ft
Explanation:
The distance is the addition of the distance gotten from both triangles.
d = x + y
d = 1178 ft + 768 ft
d = 1946 ft
