Question

Самолёту надо пролететь всего n км. Он уже пролетел c км. С какой скоростью ему надо лететь, чтобы пролететь осташийся путь за 2 часа?

Answer 1

N - с = осталось пролететь
n - с : 2 

Answer 2

Calculation of Required Speed

To determine the speed at which the plane needs to fly in order to cover the remaining distance in 2 hours, we can use the formula:

Speed = Distance / Time

Given that the plane needs to cover a total distance of n km and has already flown c km, the remaining distance is n - c km. We want to find the speed at which the plane needs to fly to cover this remaining distance in 2 hours.

Using the formula, we have:

Speed = (n - c) / 2

Therefore, the plane needs to fly at a speed of (n - c) / 2 km/h in order to cover the remaining distance in 2 hours.

Let's substitute the given values into the formula to calculate the required speed.
