Question

8. З однієї точки у протилежних напрямах одночасно почали повзти два равлика Швидкість одного з них 17,2 м/хв, а другого - на 0,9 м/хв менша. Через скільки хвилин відстань між ними буде 60,3 м?​

Answer 1

Ответ:

1,8 хв.

Пошаговое объяснение:

1)17,2-0,9=16,3 м/хв-швидкість 2 равликів

2) 17,2+16,3=33,5 м/хв

3) 60,3:33,5=1,8 хв.

Answer 2

To find out how long it will take for the distance between the two ants to be 60.3 meters, we need to calculate the time it takes for the faster ant to catch up to the slower ant.

Let's denote the speed of the faster ant as v1 (17.2 m/min) and the speed of the slower ant as v2 (0.9 m/min less than v1).

The relative speed between the two ants is the difference between their speeds: v_rel = v1 - v2.

To calculate the time it takes for the faster ant to catch up to the slower ant, we can use the formula:

time = distance / relative speed.

Plugging in the given values, we have:

time = 60.3 m / (17.2 m/min - 0.9 m/min).

Calculating this expression gives us the time it takes for the faster ant to catch up to the slower ant.

Please note that the units for speed and time need to be consistent. In this case, we are using meters and minutes.

Let's calculate the result.
