A point on a wheel moves at 27pi/5 radians per minute how many seconds are required for the point to complete 12 revolutions

Time required for the point to complete 12 revolutions; t = 266.67 seconds

Step-by-step explanation:

We are told that the angular speed is;

ω = 27π/5 rads/minute

And that number of revolutions; N = 12 revolutions

Since N is in revolutions, and we told to find time in seconds, thus let's convert the angular speed to rev/s

Thus,

ω = 27π/5 rads/minute = (27π/5) x 0.0166666667 x ½π rev/s

ω = 0.045 rev/s

Thus, N = ωt

Where t is time required

So, 12 = 0.045t

t = 12/0.045

t = 266.67 seconds

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
