A swimmer enters the water and swims in a straight line at 54 meters per minute. Another swimmer enters the water 3 minutes later, swimming in the same direction at 134 meters per minute. Which parametric equations could model the swimmers' paths from the time the first swimmer entered the water?

x(t) = 54t and y(t) = 134(t – 3)
x(t) = 54(t – 3) and y(t) = 134t
x
(t) = 54(t + 3) and y(t) = 134t
x
(t) = 54t and y(t) = 134(t + 3)
