Near the end of a marathon race, the first two runners are separated by a distance of 47m. The front runner has a velocity of 3.5m/s, and the second a velocity of 4.2m/s. What distance ahead will the winner be when she crosses the finish line?

Near the end of a marathon race, the first two runners are separated by distance of 45.0 m. The front runner has a velocity of 3.45 m/s and the second velocity of 4.20 m/s. What is the velocity of the second runner relative to the first? If the front runner is 250 m from the finish line, who will win the race, assuming they run at a constant velocity? What distance ahead will the winner be when she crosses the finish line?

Near the end of a marathon race, the first two runners are separated by a distance of 45.0 m. The front runner has a velocity of 3.45 m/s, and the second a velocity of 4.25 m/s. (a) What is the velocity of the second runner relative to the first? m/s faster than the front runner. (b) If the front runner is 250 m from the finish line, who will win the race, assuming they run at constant velocity? The first runner will win. The second runner will win. (c) What distance ahead will the winner be when she crosses the finish line?
