Answer:
133 1/3 km/hour
Step-by-step explanation:
Average speed is computed as ...
average speed = (total distance)/(total time)
= (80 km +120 km +200 km)/(2/3 + 1 + 1 1/3 hour) = 400 km/(3 hour)
= 133 1/3 km/hour

Convert cm to meters by dividing the length by 100.
4/100= = 0.04
So, this is kinda similar to the other I helped you with:
<span>So r is the radius of the disk. The area is known and equal to 100Pi; so
100Pi = Pi r2
Now for r: r = 10
Circumference = 2 PI r = 20 Pi
I hope this helped!</span>
I got 22.5
tell me if i got it wrong or right
