Question

7. Велосипедист едет со скоростью5 м/с. Какой путь он проедет за 0,5ч?с дано и решением пж​

Answer 1

Дано: V=5 м/с; t=0,5 ч=3600/2 с=1800 с; S - ?

S=V*t=5 м/с * 1800 с=9 000 м=9 км.

ИЛИ в часах

5 м/с=5*3,6=18 км/ч

S=18 км/ч * 0,5 ч=9 км.   Это ответ.

-------------------------------------

Запомните перевод

V(м/с)=V*3,6 (км/ч)

V(км/ч)=V/3,6 (м/с)

72 км/ч=72*1000 м/3600 с= 72/3,6 м/с=20 м/с и наоборот.

1 км=1000 м; 1 час=3600 с.

Answer 2

Problem Statement

A cyclist is traveling at a speed of 5 m/s. How far will the cyclist travel in 0.5 hours?

Solution

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

Distance = Speed × Time

Given: - Speed = 5 m/s - Time = 0.5 hours

First, we need to convert the time from hours to seconds, as the speed is given in meters per second. There are 3600 seconds in one hour, so 0.5 hours is equal to 0.5 × 3600 = 1800 seconds.

Now, we can substitute the values into the formula:

Distance = 5 m/s × 1800 s

Calculating the distance:

Distance = 9000 meters

Therefore, the cyclist will travel a distance of 9000 meters in 0.5 hours.

Answer

The cyclist will travel a distance of 9000 meters in 0.5 hours.
