Let the length of the race = a miles
Since, Speed =
Time taken to cover 'a' miles with the speed = 12 mph,
Time taken '' =
Time taken to cover 'a' miles with the speed = 11 mph,
Time taken '' =
Since the time taken by David to cover 'a' miles was 10 minutes Or hours more than the time he expected.

Now, we are told to leave points B and C fixed.
Now, if we move Point A to different locations, ∠ ABC will increase or decrease depending on the new location that point A is put.
Lastly, if we move Point A to a point on line CB, it means ∠ABC = 0° because it isn't subtended at any angle at all.
