Question

Самалет пролетел растояние за 1ч 15м со скоростью 440км/ч. с какой скоростью он летел обратно если из-за плохой погоды на перелет он затратил на 15 минут больше

Answer 1

Самолёт пролетел 01:30

Answer 2

Calculation of the Distance Traveled

To find the speed at which the plane flew back, we first need to calculate the distance it traveled in the initial 1 hour and 15 minutes. We know that the plane flew at a speed of 440 km/h during this time.

To calculate the distance, we can use the formula:

Distance = Speed × Time

Given that the time is 1 hour and 15 minutes, we need to convert it to hours. Since there are 60 minutes in an hour, 15 minutes is equal to 15/60 = 0.25 hours.

Now we can calculate the distance:

Distance = 440 km/h × 1.25 hours

Calculating this, we find that the plane traveled a distance of 550 kilometers.

Calculation of the Return Speed

Next, we need to determine the speed at which the plane flew back. We know that due to bad weather conditions, the return flight took 15 minutes longer than the initial flight.

To calculate the return speed, we can use the formula:

Speed = Distance / Time

Given that the distance is 550 kilometers and the time is 1 hour and 15 minutes plus an additional 15 minutes, we need to convert the total time to hours.

The total time is 1 hour and 30 minutes, which is equal to 1.5 hours.

Now we can calculate the return speed:

Speed = 550 km / 1.5 hours

Calculating this, we find that the plane flew back at a speed of approximately 366.67 km/h.

Therefore, the plane flew back at a speed of approximately 366.67 km/h.
