Question

Самолет пролетел расстояние между двумя аэропортами за 6 часов со скоростью 850 км в час .За сколько времени пролетит это расстояние другой самолет, скорость которого на 150 км в час больше скорости первого?

Answer 1

6 ч х 850 км/ч =5100 км
850 + 150= 1000 км/ч
5100 км : 1000 км/ч= 5,1 ч
ответ: 5,1 ч

Answer 2

Calculation of Time Taken by the Second Plane

To calculate the time taken by the second plane to cover the same distance, we need to consider that its speed is 150 km/h faster than the speed of the first plane, which is 850 km/h.

Let's denote the time taken by the second plane as t.

The distance covered by both planes is the same, so we can set up the following equation:

Distance covered by the first plane = Distance covered by the second plane

The distance covered by the first plane is given by the formula:

Distance = Speed × Time

For the first plane, the distance covered is the same as the distance between the two airports, and the time taken is 6 hours:

Distance1 = 850 km/h × 6 hours

For the second plane, the distance covered is also the same as the distance between the two airports, and the time taken is t hours:

Distance2 = (850 km/h + 150 km/h) × t

Setting up the equation:

Distance1 = Distance2

850 km/h × 6 hours = (850 km/h + 150 km/h) × t

Simplifying the equation:

5100 km = 1000 km/h × t

Dividing both sides by 1000 km/h:

t = 5.1 hours

Therefore, the second plane will take 5.1 hours to cover the same distance.
