Let's write some equations.
Mingwei's distance from Town A after

hours from 8:00 is

.
Ali's distance from Town B after

hours is

, since he doesn't start walking for 40 minutes.
When Mingwei's distance is twice Ali's, they've met up (since their distance from Town A is twice their distance from Town B).
So, this gives

, so

, so

, so the time is 10:40.
After

hours, Mingwei has traveled

kilometers while Ali has traveled sixty, so the distance between the towns is

kilometers.
The answer would be 115°, the sum of interior angles in a kite is always 360° so if 41° and 89° equal 130° subtract 130° from 360° and that gives you 230° divide that by two for each side of the kite missing and you get 115°
Answer:
The answer would be Set: "S" = the set of natural numbers greater than 11.
Hope this helps!
