Автомобиль за 10 часов проезжает такое же расстояние, какое самолет пролетает за 1 час. Скорость самолета 900 км/ч. Определить скорость автомобиля и найти, во сколько раз она меньше скорости самолета.
1. Расстояние, которое пролетит самолет за 1 час при скорости v₁ = 900 км/ч: S = v₁t₁ = 900*1 = 900 (км) 2. Скорость автомобиля: v₂ = S/t₂ = 900 : 10 = 90 (км/ч) 3. v₁/v₂ = 900/90 = 10
