From the table, the speed of Corinne is given by From the graph, the speed of Aretha is given by The distance from the starting point of Corinne at any time t is given by D = 0.125t while the distance from the starting point of Aretha at any time t is given by D = 3.5 + 0.1t Let t be the number of minutes after the start of the race when Corinne catchs Aretha, then 0.125t = 3.5 + 0.1t 0.025t = 3.5 t = 3.5 / 0.025 = 140 Therefore, the number of minutes after the start of the race that Corinne will catch Aretha is 140 minutes.
