Here's a visual representation. The numbers are a little blurry though.
Answer:
If she travels 1 block every minute, it will take her 24 minutes to get to her friends house. If she travels 2 blocks every minute it will take her 12 minutes to get there.
Step-by-step explanation:
24 blocks ÷ 1 minutes = 24 minutes
24 blocks ÷ 2 minutes = 12 minutes
Add E on AB where ED is perpendicular to AB , since the distance between D and AB is 5 in , so ED is 5 in (because the distance between a point and a line is the length of the perpendicular line drawn from the point to the line)
now we have a right angled triangle AED at E , sin(DAE) = DE/AD = 5/10 =1/2
so angle DAE is 30 degrees and since angle CAB is 60 degrees
therefore AD is angle bisector of angle A
