B) Based off the previous answer she should be 0.25 miles ahead of you by the time you start walking. For this problem you would need a graph, the equations for the graph I got were y=3x+0.25 and y=4x+0. Simply graph after this and find the intercept, to determine the amount of time it took you need to view where the two lines intercept, and the x value is the amount of time it took. The x value I got was 0.25. So 60*0.25 is 15, it took you 15 minutes to catch up with her at 1 miles from the start point.
