To determine how long it will take for both Silvio and Fernando to arrive at the café, we need to find the intersection point of the two lines, S(m) and F(m), on the graph. The coordinates of the intersection point will provide the time in minutes at which both reach the café.
Since I cannot see the graph, I cannot provide you with the exact answer. However, you can locate the intersection point of the lines and read off the time value from the x-axis or y-axis, depending on how the graph is labeled. Based on the options provided, it could be any of the following: 60 minutes, 20 minutes, 0 minutes, or 28 minutes.
Please refer to the graph to find the intersection point and determine the correct time.
