You can put this solution on YOUR website!
Let t be the expected time;
Let d be the distance from A to B.
10 minutes is 1%2F6 hour;
16 minutes is 4%2F15 hour.


___________________speed____________time_____________distance________Equations
Late_______________40_______________t+1/6____________d_______________40%28t%2B1%2F6%29=d
Later______________30_______________t+4/15___________d_______________30%281%2B4%2F15%29=d

That should be enough for you to continue to the finish. Two equations and two unknown variables.
