Gọi độ dài quãng đường từ A đến B là x(km)
(Điều kiện: x>0)
Thời gian Ben đi từ A đến B nếu đi với vận tốc 10km/h là: \(\frac{x}{10}\) (giờ)
Thời gian Ben đi từ A đến B nếu đi với vận tốc 15km/h là: \(\frac{x}{15}\) (giờ)
10h cách 8h là: 10h-8h=2h
=>\(\frac{x}{10}-\frac{x}{15}=2\)
=>\(\frac{3x}{30}-\frac{2x}{30}=2\)
=>\(\frac{x}{30}=2\)
=>x=60(nhận)
Khi Ben đi từ A đến B với vận tốc 15km/h thì thời điểm Ben xuất phát là:
\(8h-\frac{60}{15}h=4h\)
Thời gian từ 4h đến 9h là:
9-4=5(giờ)
Vận tốc Ben cần đi là 60:5=12(km/h)
