Answer:
80km/h
Step-by-step explanation:
The answer is c-one 1/2 is the same as 4/8 if you think about it is very easy. Watch since 4/8 is equal to 1/2 that means 3/6,2/4,5/10,12/6 and 32/64 are all equal because all you have to do is divide the denominator in half and that becomes the numerator and it is equivalent to 1/2.
X(1/2) = 12
x(1/2)(2) = 12(2)
x(1) = 24
x = 24
hope this helps

-18
Step-by-step explanation:
Answer:
- angular speed: 61.3 radians/s
- tangential speed at .193 m: 11.8 m/s
Step-by-step explanation:
The forward speed of the center of the tire with respect to the ground is the same as the tangential speed of the tire at its full radius of 0.315 m, relative to the axle.
The angular speed of the tire is the ratio of tangential speed to radius:
(19.3 m/s)/(0.315 m) ≈ 61.27 radians/s
The tangential speed at any other radius is the product of angular speed and radius. At a radius of 0.193 m, the tangential speed is ...
(0.193 m)×(19.3 m/s)/(0.315 m) ≈ 11.825 m/s ≈ 11.8 m/s
