Question

За 40 мин пешеход прошел 3 километра . Сколько километров он пройдет за 1 час если будет идти с той же скоростью??

Answer 1

4,5 км он пройдет за 1 час в 3000метоов: на 40 мин 3000:40=75 м в 1 мин 75×20 так как в 1часе 60 мин 1500 метров пройдет за 20 мин общее 4500 метров за час итого 4,5 км

Answer 2

Calculation of Distance Covered in 1 Hour

To calculate the distance covered in 1 hour, we need to determine the speed at which the pedestrian is walking. Since the pedestrian covered 3 kilometers in 40 minutes, we can calculate the speed using the formula:

Speed = Distance / Time

Given that the distance covered is 3 kilometers and the time taken is 40 minutes, we can substitute these values into the formula:

Speed = 3 kilometers / 40 minutes

To convert the time from minutes to hours, we divide by 60:

Speed = 3 kilometers / (40 minutes / 60 minutes per hour)

Simplifying the equation:

Speed = 3 kilometers / (2/3 hours)

To divide by a fraction, we multiply by its reciprocal:

Speed = 3 kilometers * (3/2 hours)

Canceling out the units:

Speed = 9/2 kilometers per hour

Therefore, the pedestrian is walking at a speed of 4.5 kilometers per hour.

Now, to calculate the distance covered in 1 hour, we multiply the speed by the time:

Distance = Speed * Time

Substituting the values:

Distance = 4.5 kilometers per hour * 1 hour

Simplifying the equation:

Distance = 4.5 kilometers

Therefore, the pedestrian will cover 4.5 kilometers in 1 hour if they continue walking at the same speed.
