Question

1.V=0,5 км/ч S=150.000 м t=? - 2.V=20 км/ч t=30 дней S=? - 3.V1=1 км/ч|v2=3м/с|v3=3м/ч t=5c|t2=1ч|t3=15c

Answer 1

Ответ:

1. Переводим в км 150000 м = 150 км

Расстояние ищется по формуле

S= v*t, выражаем t

t= S/v

t = 150/0.5 = 300 часов

Ответ: 300 часов

2. Переводим 30 дней в часы

в сутках 24 часа следовательно

30 * 24 = 720 часов

Формула расстояния S = v*t

S = 720 * 20 = 14400 км

3. Вопроса нет, но я думаю, нужно найти S

Переведем V1 в м/с

1*1000/3600= 0.28 м/с

S1 = 0.28 * 5 = 1.4 м

Переведем t2 в секунды

1*60*60= 3600 с

S2 = 3600 * 3 = 10800 м

Переведем V3 в м/с

3*1000/3600 = 0.84 м/с

S3 = 0.84 * 15 = 12.6 м

Answer 2

1. To find the value of time (t), we can use the formula: t = S / V

   Given: V = 0.5 km/h S = 150,000 m

   First, we need to convert V to m/s: V = 0.5 km/h * (1000 m/km) / (3600 s/h) = 0.1389 m/s

   Now we can calculate t: t = 150,000 m / 0.1389 m/s ≈ 1,080,108 seconds

   Therefore, t is approximately 1,080,108 seconds.

2. To find the value of distance (S), we can use the formula: S = V * t

   Given: V = 20 km/h t = 30 days

   First, we need to convert V to m/s: V = 20 km/h * (1000 m/km) / (3600 s/h) = 5.56 m/s

   Now we need to convert t to seconds: t = 30 days * 24 hours/day * 60 minutes/hour * 60 seconds/minute = 2,592,000 seconds

   Now we can calculate S: S = 5.56 m/s * 2,592,000 s ≈ 14,387,200 meters

   Therefore, S is approximately 14,387,200 meters.

3. Given: V1 = 1 km/h V2 = 3 m/s V3 = 3 m/h

   t1 = 5 seconds t2 = 1 hour t3 = 15 seconds

   The distances covered can be calculated using the formula: S = V * t

   For the first case: V1 = 1 km/h * (1000 m/km) / (3600 s/h) = 0.2778 m/s t1 = 5 seconds S1 = 0.2778 m/s * 5 s = 1.389 meters

   For the second case: V2 = 3 m/s t2 = 1 hour * 60 minutes/hour * 60 seconds/minute = 3600 seconds S2 = 3 m/s * 3600 s = 10,800 meters

   For the third case: V3 = 3 m/h * (1/3600) h/s = 0.0008333 m/s t3 = 15 seconds S3 = 0.0008333 m/s * 15 s = 0.0125 meters

   Therefore, the distances covered are: S1 = 1.389 meters S2 = 10,800 meters S3 = 0.0125 meters
