By definition we have to:
v = d / t
Where,
v: speed
d: distance
t: time
The time in hours is given by:
t = 4 + (45/60)
t = 4.75 hours
Substituting values we have:
v = 456 / 4.75
v = 96 km / h
Answer:
the speed of the train is:
v = 96 km / h
Answer:
C
Step-by-step explanation:
Area of a 1/4 sector of a circle = 1/4 * pi r^2
Givens
100 of these quarter sectors
pi = 3.14
r = 12
Solution
You are using area because you are going to paint each one of the sectors. You must cover every cm^2 with paint.
Area = 1/4 * 3.14 * r * r
Area = 1/4 * 3.14 * 12 * 12
Area = 113.25
But there are 100 of them. so the area is
100 * Area = 11325 cm^2
Rounded to the nearest 100 hundreds = 11300 cm^2
