Arnold and Juju are 140 m apart. Arnold can run at a speed of 8 m/s while Juju can run at a speed of 6m/s. If the two boys run at the same instant, straight towards each other, when and where will they meet?
They approach each other with a speed . Therefore, time when they meet is , 10 seconds. During this time, Arnold will run from his initial position, so that's where they will meet (we can equivalently say that they will meet 60m from Juju's initial position).
