jimi runs round a track in 12 min and charlie runs round the same track in 18 min. if they start in the same place at the same tim, how many minutes will pass before they both cross the start line again? Charlie decides to get in shape, he now is able to run the lap in 14 min. How long would it take for them to meet at the start again?

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
