Andrew walks 3/4 mile in 10 minutes. Jill walked 4/5 in 15 minutes. What was the difference in their speeds, in miles per hour?

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
