Question

Два автомобілі перебувають на відстані 4395м один від одного. Одночасно вони починають рухатися у протилежних напрямках зі швидкостями 560м/хв і 712 м/хв. Якою буде відстань між ними через 3 хвилини?

Answer 1

Ответ:

1)S1=560*3=1680 м

2)S2=712*3=2136 м

3)4395+1680+2136=8211 м

Відповідь: відстань між автомобілями через 3 хвилини - 8211 м

Answer 2

To find the distance between two cars moving in opposite directions, we can use the formula:

Distance = (Speed of Car 1 + Speed of Car 2) * Time

Given that the two cars are initially 4395m apart and are moving with speeds of 560m/min and 712m/min, respectively, we can calculate the distance between them after 3 minutes.

Calculation:

Using the formula mentioned above, we can calculate the distance between the two cars after 3 minutes:

Distance = (560m/min + 712m/min) * 3 min

To calculate this, we need to convert the speeds from meters per minute to meters per second, as the time is given in minutes.

Converting the speeds: - Speed of Car 1 = 560m/min = 560/60 m/s - Speed of Car 2 = 712m/min = 712/60 m/s

Now, we can calculate the distance:

Distance = ((560/60) m/s + (712/60) m/s) * 3 min

Calculating the speeds in meters per second: - Speed of Car 1 = 560/60 m/s = 9.333 m/s - Speed of Car 2 = 712/60 m/s = 11.867 m/s

Substituting the values into the formula:

Distance = (9.333 m/s + 11.867 m/s) * 3 min

Calculating the sum of the speeds:

Distance = (21.2 m/s) * 3 min

Converting the time from minutes to seconds:

Distance = (21.2 m/s) * 180 s

Calculating the final distance:

Distance = 3816 m

Therefore, the distance between the two cars after 3 minutes will be 3816 meters.
