Question

самолёт пролетает 3600км за 4 ч .Сколько времени понадобится вертолёту, чтобы пролететь такое же расстояние,если его скорсть в 4 раза меньше скорости самолёта?За какое время вертолёт пролетит 3825км,если бутет двигаться с той же скорстью? с таблицей V t s

Answer 1

                                    V, км/ч                    t, ч.                     S, км

самолёт                         ?                            4                        3600

вертолёт           ? в 4 р. < V cамол.            ?                        3600

вертолёт           ? в 4 р. < V cамол.            ?                        3825

 

1) 3600:4=900 (км/ч) - скорость самолёта

2) 900:4=225 (км/ч) - скорость вертолёта

3) 3600:225=16 (ч.) - время на преодоление 3600 км

4) 3825:225=17 (ч.) - время на преодоление 3825 км

Ответ: вертолёт пролетит расстояние 3600 км за 16 часов; расстояние 3825 км - за 17 часов.

Answer 2

Calculation of Time for Helicopter to Cover the Same Distance

To calculate the time it would take for a helicopter to cover the same distance as the airplane, we need to consider that the helicopter's speed is 4 times slower than the speed of the airplane.

Given that the airplane covers a distance of 3600 km in 4 hours, we can calculate the speed of the airplane using the formula:

Speed = Distance / Time

Therefore, the speed of the airplane is:

Speed of airplane = 3600 km / 4 hours = 900 km/h.

Since the helicopter's speed is 4 times slower than the airplane's speed, we can calculate the speed of the helicopter:

Speed of helicopter = Speed of airplane / 4 = 900 km/h / 4 = 225 km/h.

Now, to calculate the time it would take for the helicopter to cover the same distance, we can use the formula:

Time = Distance / Speed

Substituting the values, we get:

Time for helicopter = 3600 km / 225 km/h = 16 hours.

Therefore, it would take the helicopter 16 hours to cover the same distance as the airplane.

Calculation of Time for Helicopter to Cover 3825 km

To calculate the time it would take for the helicopter to cover a distance of 3825 km, assuming it maintains the same speed as before (225 km/h), we can use the formula:

Time = Distance / Speed

Substituting the values, we get:

Time for helicopter = 3825 km / 225 km/h = 17 hours.

Therefore, it would take the helicopter 17 hours to cover a distance of 3825 km at the same speed.

Table: Relationship between Velocity, Time, and Distance

| Velocity (V) | Time (t) | Distance (s) | |--------------|----------|--------------| | 900 km/h | 4 hours | 3600 km | | 225 km/h | 16 hours | 3600 km | | 225 km/h | 17 hours | 3825 km |

Please note that the values in the table are based on the calculations mentioned above and assume a constant speed for the helicopter.
