Watch closely. I'll try to go slow.
Stop me if I go too fast, or if I do anything that you don't understand.
Ready ?
You said d = r t
Divide each side by ' t ' : d / t = r
Answer:
The linear speed in which Darlene is traveling is 24.74 miles per hour.
Step-by-step explanation:
The wheel experiments rolling, which is a combination of translation and rotation. The point where linear speed happens is located at geometrical center of the wheel and instantaneous center of rotation is located at the point of contact between wheel and ground. The linear speed (
), measured in inches per second, is defined by following expression:
(1)
Where:
- Radius of the wheel, measured in inches.
- Angular speed, measured in radians per second.
If we know that
and
, then the linear speed, measured in miles per hour, in which Darlene is traveling is:


The linear speed in which Darlene is traveling is 24.74 miles per hour.
4800 meters per 60 minutes
Divide 4800 meters by 60 minutes
80meters per minute
X is 65 because 65 is great and should always be the answer
Step-by-step explanation:
x=8-y
2x-y=7
2(8-y)-y=7
16-2y-y=7
-3y=-9
y=3
x=8-y
x=8-3=5
