Question

Биатлонист проходит дистанцию 4 км за 3,5мин. С какой скоростью он движется?

Answer 1

4*3/5
потому что мы больше не как не узнаем и при этом там какая скорость

Answer 2

Calculation of Speed

To calculate the speed at which the biathlete is moving, we can use the formula:

Speed = Distance / Time

Given that the distance covered is 4 km and the time taken is 3.5 minutes, we can substitute these values into the formula to find the speed.

Speed = 4 km / 3.5 min

To simplify the calculation, let's convert the time from minutes to hours. There are 60 minutes in an hour, so 3.5 minutes is equal to 3.5/60 hours.

Speed = 4 km / (3.5/60) hours

Simplifying further:

Speed = 4 km / 0.0583 hours

Now, let's calculate the speed:

Speed ≈ 68.6 km/h

Therefore, the biathlete is moving at a speed of approximately 68.6 km/h
