Andy and Donald are both running toward the soccer ball during a game.

Andy's path is represented by the parametric equations x (t) = 24+2/3t, y (t) = 8+16t, where t is on the interval [0,50] and t is measured in tenths of seconds.

Donald's path is represented by the parametric equations x (t) = 12+t, y (t) = 5+1/4t, where t is on the interval [0,50] and t is measured in tenths of seconds.

Do the boys collide? If so, when do they collide?

Andy and Donald do not collide.

Andy and Donald collide at 4.8 seconds.

Andy and Donald collide at 2.4 seconds.

Andy and Donald collide at 3.6 seconds.
