Question

За 20 минут велосипедист проехал 7 километров. Сколько километров он проедет за 35 минут, если будет ехать с той же скоростью?

Answer 1

7:20=0,35 км\мин   скорость велосипедиста
0,35*35=12,25 км  он проедет за 35 мин

Answer 2

Дано
t1=1200c
s1=7000м
t2=2100c
 найти
s(t2)-?
Решение
v=s:t=7000:1200=5,83м/c
s=v*t=5.83м/c*2100=12243м

Answer 3

Problem Analysis

We are given that a cyclist traveled 7 kilometers in 20 minutes. We need to determine how many kilometers the cyclist will travel in 35 minutes if they maintain the same speed.

Solution

To solve this problem, we can use the concept of speed. Speed is defined as the distance traveled per unit of time. Since the cyclist is traveling at a constant speed, we can assume that the speed remains the same.

We can set up a proportion to solve for the distance traveled in 35 minutes. Let's denote the distance traveled in 35 minutes as x kilometers. The proportion can be set up as follows:

7 kilometers / 20 minutes = x kilometers / 35 minutes

To solve for x, we can cross-multiply and then divide:

7 kilometers * 35 minutes = 20 minutes * x kilometers

x kilometers = (7 kilometers * 35 minutes) / 20 minutes

Now we can calculate the value of x:

x kilometers = (7 * 35) / 20 = 12.25 kilometers

Therefore, the cyclist will travel approximately 12.25 kilometers in 35 minutes if they maintain the same speed.

Answer

The cyclist will travel approximately 12.25 kilometers in 35 minutes if they maintain the same speed.
