Jon begins jogging at a steady rate of 3 meters per second from the left side of lane 1. Laura also starts at the left side, but jogs at a rate of 4 meters per second in lane 2. Ellis starts at the right side of lane 4, 100 meters down the track, and runs towards Jon and Laura at the rate of 6 meters per second. After t seconds, Jon, Laura, and Ellis all lie in a straight line. Compute t.
I know that the answer is apparently 8 and 1/3, but how exactly do you get 8 and 1/3?
