Question

Летчик на реактивном самолете пролетел путь равный 45 км в течение 2,5 минут Определите скорость самолета

Answer 1

42:2,5=16,8 (км/ч) -Скорость

Answer 2

Calculation of the Speed of the Jet

To determine the speed of the jet, we can use the formula:

Speed = Distance / Time

Given that the jet traveled a distance of 45 km in a time of 2.5 minutes, we can substitute these values into the formula:

Speed = 45 km / 2.5 min

To calculate the speed, we need to convert the time from minutes to hours, as the speed is typically measured in kilometers per hour. There are 60 minutes in an hour, so we divide the time by 60:

Speed = 45 km / (2.5 min / 60 min/h)

Simplifying the equation:

Speed = 45 km / (2.5/60) h

Now, let's calculate the speed using the given values:

Speed = 45 km / (2.5/60) h = 45 km / (0.0417) h ≈ 1079.52 km/h

Therefore, the speed of the jet is approximately 1079.52 km/h.
