In a 200 m race, the runner who finished first was ahead of the 2nd runner by 40 m and ahead of the 3rd runner by 80 m. What was the distance (in meters) between the 2nd runner and the 3rd runner when the 2nd runner reached the finish line ? It is assumed that the three runners maintain their (constant) speeds throughout the race.

The second runner was 40m ahead of the 3rd runner because the first runner finished 40m in front of the 2nd runner and 80m in front of the 3rd. To find the distance in between the 2nd runner and 3rd runner we do the following, 80m - 40m = 40m
