The graph represents the speed at which Pete’s marble travels. The speed of Stephano’s marble is represented by the equation f = 2.25s, where f is the distance in feet and s is the time in seconds.
Whose marble will reach the 6-foot mark sooner?

Graph of a diagonal line on a coordinate plane going up and to the right with Time (s) on x-axis and Distance (ft) on y-axis. When s is 0, ft is 0. When s is 4, ft is 6
