Question

Велосипедист за 40 мин проехал 10 км.За сколько времени он проедет еще 25 км, двигаясь с той же скоростью? (Только решение нужно сделать в виде таблицы: дано, найти, решение, СИ, ответ). Заранее спасибо!

Answer 1

Дано: 40 мин = 10 км, ?мин = 25 км, км/ч1 = км/ч2
Найти: км/ч и t2
Решение: 10:40= 0,25 км/ч 25:0,25=100 мин
Ответ: чтобы проехать 25 км с той же скоростью, нужно ехать 100 мин или 1 ч 40 мин

Answer 2

Given:

- Distance traveled in 40 minutes: 10 km - Distance to be traveled: 25 km - Speed remains the same

To find:

- Time required to travel an additional 25 km

Solution:

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time required to travel the initial 10 km using the given information:

| Given | Formula | Calculation | |-------|---------|-------------| | Distance (s) | 10 km | | | Speed (v) | | | | Time (t) | | |

We are given that the distance traveled in 40 minutes is 10 km. To find the speed, we can use the formula speed = distance / time. Since the time is given in minutes, we need to convert it to hours by dividing by 60.

| Given | Formula | Calculation | |-------|---------|-------------| | Distance (s) | 10 km | | | Speed (v) | | | | Time (t) | 40 minutes | 40 / 60 = 2/3 hours |

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

| Given | Formula | Calculation | |-------|---------|-------------| | Distance (s) | 10 km | | | Speed (v) | 10 km / (2/3) hours | 10 * (3/2) km/h = 15 km/h | | Time (t) | 40 minutes | 2/3 hours |

Now that we have the speed, we can calculate the time required to travel an additional 25 km:

| Given | Formula | Calculation | |-------|---------|-------------| | Distance (s) | 25 km | | | Speed (v) | 15 km/h | | | Time (t) | | |

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

| Given | Formula | Calculation | |-------|---------|-------------| | Distance (s) | 25 km | | | Speed (v) | 15 km/h | | | Time (t) | 25 km / 15 km/h | 5/3 hours |

Answer:

The cyclist will take 5/3 hours to travel an additional 25 km, moving at the same speed.

Solution in Table Format:

| Given | Formula | Calculation | |-------|---------|-------------| | Distance (s) | 10 km | | | Speed (v) | 10 km / (2/3) hours | 15 km/h | | Time (t) | 40 minutes | 2/3 hours | | Distance (s) | 25 km | | | Speed (v) | 15 km/h | | | Time (t) | 25 km / 15 km/h | 5/3 hours |

Note: The calculations are rounded to the nearest decimal place.
