Question

От посёлка до станции 2,7 км. Андрей проходит это расстояние пешком за 0,6 ч. За какое время он проезжает это расстояние на велосипеде ,если на велосипеде он едет со скоростью ,на 6,3 км/ч большей ,чем идет пешком?(помогите решить )

Answer 1

1)2.7:0.6=4.5(км\ч)-скорость пешком.

2)4.5+6.3=10.8(км\ч)-скорость на велосипеде

3)2.7:10.8=0.25(ч)-пройдет

Ответ:0.25 часа

 

Answer 2

Находим скорость пешком

2,7:0,6=4,5 км/час

Находим скорость на лисапете

4,5+6,3=10,8 км/час

Находим время на лисапете

2,7:10,8=0,25 часа т.е. 15 мин

Answer 3

Problem Analysis

Andrey needs to determine the time it takes for him to travel a distance of 2.7 km on a bicycle, given that he can walk the same distance in 0.6 hours. The bicycle speed is 6.3 km/h faster than his walking speed.

Solution

To find the time it takes for Andrey to travel the distance on a bicycle, we need to calculate the time using the formula: time = distance / speed.

Let's calculate the time it takes for Andrey to walk the distance of 2.7 km: - Distance: 2.7 km - Walking speed: unknown - Time: 0.6 hours

Using the formula, we can calculate the walking speed: walking speed = distance / time

Now, let's calculate the time it takes for Andrey to cycle the same distance: - Distance: 2.7 km - Cycling speed: walking speed + 6.3 km/h (since the cycling speed is 6.3 km/h faster than the walking speed) - Time: unknown

Using the formula, we can calculate the cycling time: cycling time = distance / cycling speed

Let's calculate the walking speed first.

Calculation

Walking speed: - Distance: 2.7 km - Time: 0.6 hours

walking speed = distance / time = 2.7 km / 0.6 hours = 4.5 km/h.

Now, let's calculate the cycling time.

Cycling time: - Distance: 2.7 km - Cycling speed: walking speed + 6.3 km/h = 4.5 km/h + 6.3 km/h = 10.8 km/h

cycling time = distance / cycling speed = 2.7 km / 10.8 km/h = 0.25 hours.

Answer

Andrey can travel the distance of 2.7 km on a bicycle in 0.25 hours.
