Hiệu vận tốc là:

\(40-8=32\left(km/h\right)\)

Thời gian để gặp nhau là:

\(\dfrac{50}{32}=\dfrac{25}{16}\) (giờ)

Quãng đường xe đạp đi được là:

\(8\cdot\dfrac{25}{16}=12,5\left(km\right)\)

 Quãng đường xe máy đi được là:

\(40\cdot\dfrac{25}{16}=62,5\left(km\right)\) (đi từ A đến B rồi quay lại \(12,5km\))

\(\rightarrow\) Lần gặp nhau thứ nhất xảy ra tại vị trí cách A \(12,5km\)

Sau lần gặp nhau thứ nhất, xe máy tiếp tục đi từ vị trí gặp nhau \(12,5km\) từ A đến B xong quay lại

Thời gian để xe máy đi từ vị trí gặp nhau đến B và quay lại vị trí gặp nhau là:

\(\dfrac{50-12,5}{40}+\dfrac{50}{40}=\dfrac{87,5}{40}\) (giờ)

Quãng đường xe đạp đi được trong thời gian này là:

\(8\cdot\dfrac{87,5}{40}=17,5\left(km\right)\)

Quãng đường xe máy đi được trong thời gian này là:

\(40\cdot\dfrac{87,5}{40}=87,5\left(km\right)\) (đi từ A đến B rồi quay lại \(37,5km\))

\(\rightarrow\)Lần gặp nhau thứ hai xảy ra tại vị trí cách A \(17,5km\)

a: Xét (O) có

AB,AC là các tiếp tuyến

Do đó: AB=AC

=>A nằm trên đường trung trực của BC(1)

Ta có: OB=OC

=>O nằm trên đường trung trực của BC(2)

Từ (1),(2) suy ra AO là đường trung trực của BC

b: Xét (O) có

ΔCBD nội tiếp

CD là đường kính

Do đó: ΔCBD vuông tại B

=>CB\(\perp\)BD

mà AO\(\perp\)BC

nên AO//BD
