Sailor ran 3/4 mile in 9 minutes express her speed as a unit rate, in miles per hour

Hello,

v=(3/4)/9 (mi/min)= (3/4)/(9/60) (mi/h)= 3/4*60/9 (mi/h)=5 (mi/h)

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
