Question

Путь S, если V=124км/ч и t=10ч; скорость V, если S=195м и t=15мин

Answer 1

путь=124х10=1240 км

скорость=расстояние: время=195:15=13 км/ч

Answer 2

Ответ:

1) S = 1240км.

2) V = 13м/мин.

Пошаговое объяснение:

1)

S = V * t

S = 124км/ч * 10ч = 1240км.

2)

V = S / t

V = 195м / 15мин = 13м/мин.

Answer 3

To find the distance (S) when you have the velocity (V) and time (t), you can use the formula:

$S = V \times t$

where: S = distance in kilometers (km), V = velocity in kilometers per hour (km/h), t = time in hours (h).

1. Given V = 124 km/h and t = 10 hours: $S = 124 \, \text{km/h} \times 10 \, \text{h}$ $S = 1240 \, \text{km}$

So, the distance (S) is 1240 kilometers.

2. Given S = 195 meters and t = 15 minutes, we need to convert t to hours since the velocity is given in km/h:

$t = 15 \, \text{min} = \frac{15}{60} \, \text{h} = 0.25 \, \text{h}$

Now, we can find the velocity (V) using the given values:

$V = \frac{S}{t}$

$V = \frac{195 \, \text{m}}{0.25 \, \text{h}}$

Before calculating, we need to ensure that the units are consistent. We have the distance in meters (m) and the time in hours (h), so we need to convert the distance to kilometers (km) since the velocity will be in km/h:

$195 \, \text{m} = 0.195 \, \text{km}$

Now, we can calculate the velocity:

$V = \frac{0.195 \, \text{km}}{0.25 \, \text{h}}$ $V = 0.78 \, \text{km/h}$

So, the velocity (V) is 0.78 kilometers per hour.
