S1=93км/ч t1=1,5чS2=147км/ч t2=2,5чU=? Решение? ​

Answer 1

Ответ:

S1=93км/ч t1=1,5ч

S2=147км/ч t2=2,5ч

U=?

Решение:

Uср=

$\frac{s1 + s2}{t1 + t2} = \frac{93 + 147}{1.5 + 2.5} = \frac{240}{4} = 60km$

=60км/ч

Ответ:60(км/ч)

Answer 2

Пошаговое объяснение:

Как мы знаем ,чтобы найти V надо S разделить на t

V¹=S¹÷t¹

V¹=93÷1,5

V¹=62

V²=S÷t

V²=147÷2,5

V²=58,8

Ответ: V¹=62 ,а V²=58,8

Answer 3

To find the value of U, we can use the formula for speed:

Speed = Distance / Time

We are given two sets of information:

1. Speed (S1) = 93 km/h, Time (t1) = 1.5 hours
2. Speed (S2) = 147 km/h, Time (t2) = 2.5 hours

We want to find the value of U, but it's not clear what U represents in this context. If U is meant to be speed, then let's use the formula to calculate the speed:

For the first set of information: Speed (S1) = Distance / Time 93 km/h = Distance / 1.5 h Distance = 93 km/h * 1.5 h Distance = 139.5 km

For the second set of information: Speed (S2) = Distance / Time 147 km/h = Distance / 2.5 h Distance = 147 km/h * 2.5 h Distance = 367.5 km

Now, if U represents a third speed, and you're looking for the time it takes to cover a certain distance at speed U, you can use the formula: Time = Distance / Speed

Let's say the distance is D and the speed is U:

Time = D / U

However, I don't have the specific values for distance and speed (U) in your problem statement, so I can't provide a numerical solution. If you provide more information about what U represents, I can help you solve the problem further.
