1) 800-480=320 (на 320 км больше пролетел 2 вертолет) 2) 320:2=160(км/час) скорость вертолетов 3) 480:160=3(часа) летал 1 вертолет 4) 800:160=5(часов) летал 2 вертолет Ответ: 1 вертолет -3 часа, 2 вертолет-5 часов

1) 800 - 480 = 320 (км) разница пройденного расстояния;
2) 320 : 2 = 160 (км/ч) скорость вертолетов;
3) 480 : 160 = 3 (ч) время полета первого вертолета;
4) 800 : 160 = 5 (ч) время полета второго вертолета.
Ответ: 3 ч, 5 ч.
