Dịch : Nhà John cách công viên 3000 m.John đi bộ từ nhà tới công viên với vận tốc 100m/phút rồi về nhà với vận tốc 150m/phút.Tính vận tốc trung bình của John (đơn vị m/phút).

Giải : John đi từ nhà tới công viên mất : 3000 : 100 = 30 (phút)

John đi từ công viên về nhà mất : 3000 : 150 = 20 (phút)

Quãng đường mà John đi là : 3000 x 2 = 6000 (m)

Thời gian John đi và về là : 30 + 20 = 50 (phút)

Vận tốc trung bình của John là : 6000 : 50 = 120 (m/phút)
