Question

Расстояние от посёлка до станции пешеход прошел за 2,5 ч,а велосипедист проехал за 5 минут. Какова скорость пешехода,если скорость велосипедиста 10,8 км/ч?

Answer 1

5\60=1\12часа
1)10.8*1\12=108\10*1\12=9\10=0.9км-расстояние
2)0.9:2.5=0.36км\ч-скорость пешехода.

Answer 2

5 мин = 1/12 часа
1) 10,8 * 1/12 = 0,9 км - расстояние от поселка до станции
2) 0,9 : 2,5 = 0,36 км/ч - скорость пешехода

Answer 3

Calculation of the Pedestrian's Speed

To calculate the pedestrian's speed, we need to determine the distance traveled by the pedestrian and the time taken.

Given: - The cyclist's speed is 10.8 km/h. - The pedestrian took 2.5 hours to walk the distance. - The cyclist took 5 minutes to cover the same distance.

Let's calculate the distance traveled by the cyclist first.

Calculation of the Distance Traveled by the Cyclist

To calculate the distance traveled by the cyclist, we can use the formula:

Distance = Speed × Time

Given: - Speed of the cyclist = 10.8 km/h - Time taken by the cyclist = 5 minutes = 5/60 hours (converted to hours)

Using the formula, we can calculate the distance traveled by the cyclist:

Distance = 10.8 km/h × (5/60) h

Simplifying the calculation:

Distance = 10.8 km/h × 0.0833 h

Distance = 0.8994 km

Now that we have the distance traveled by the cyclist, we can calculate the pedestrian's speed.

Calculation of the Pedestrian's Speed

To calculate the pedestrian's speed, we can use the formula:

Speed = Distance / Time

Given: - Distance traveled by the pedestrian = 0.8994 km - Time taken by the pedestrian = 2.5 hours

Using the formula, we can calculate the pedestrian's speed:

Speed = 0.8994 km / 2.5 h

Simplifying the calculation:

Speed = 0.35976 km/h

Therefore, the speed of the pedestrian is approximately 0.35976 km/h.
