Question 828223
Assuming that a table saw blade has a diameter of 10 inches and spins at 3450 revolutions per minute (RPMs), use unit conversion techniques you have learned in the material in 2A to determine how fast the tip of the teeth of the saw blade are traveling in miles per hour. (Remember that 1 revolution = pi x diameter = circumference.
***
{{{3450(rev/min)10(pi)(inches/rev)(ft/12 inches)(60 min/hr)(mile/5280 ft)=((3450*10(pi)*60)/(12*5280))(miles/hr)=102.67(miles/hr)}}}
rev,min,inches,ft, cancel out, leaving miles/hr.
