bài này khó, phải tìm vnuoc va vxuong 1 lúc
xuôi dòng: s/(vxuong + vnuoc) = 2h => 60/(vnuoc + vxuong) = 2
ngược dòng: s/(vxuong - vnuoc) = 4h => 60/(vxuong - vnuoc) = 4
vxuong = 22,5 km/h
vnuoc = 7,5 km/h

bài này hay ở chỗ con ong cứ bay qua bay lại nhưng thời gian thi lại đúng = thoi gian 2 xe gap nhau
+ thoi gian 2 xe gap nhau la:
t = s/(v1 +v2) = 100/(30+20) = 2h
quãng duong con ong bay la:
s = v.t = 60.2 = 120km
nhập kq (120)
CÂU7: đi xuôi : vnuoc + vxuong may = s/t = 60/2 = 30km/h
đi ngược: vxuong may - vnuoc = s/t = 60/4 = 15km/h
vậy vnuoc = (30- 15) / 2 = 7,5km/h
nhập kq (7,5 km/h)
