40 sets of tires. I learned this by looking up your question because it is incomplete.
V = rw
where; v = velocity , r = radius , w = angular speed
you're given the diameter = 0.5 miles so the radius = 0.25 miles
180 = (0.25)w
180/0.25 = w
720 radians per hour = w
2pi radians in 1 revolution
720 rad/hr * 1 rev / 2pi rad = 720/2pi rev/hr
= 114.6 rev/hr
Answer:
49 & 60
Step-by-step explanation:
294+66=362(miles) divided by 6( hours) = 60
so x=5
substituting for x in the equation we get:
