Question

S = 84 км, V = 12 км/ч, t = ?

Answer 1

S = 84 км
V = 12 км/ч
t = ? ч

t = S : V
t = 84 : 12 = 7 (ч)

Ответ: t = 7 ч.

Answer 2

$s = 84 \: km \: \: v = 12 \: km.ch \: \: t = 84 \div 12 = 7$

Answer 3

We can use the formula:

S = V * t

where: S = distance V = velocity (speed) t = time

to find the time t it takes to travel a distance S at a speed V.

In this case, we are given: S = 84 km V = 12 km/h

Substituting these values into the formula, we get:

84 km = 12 km/h * t

To solve for t, we can divide both sides by 12 km/h:

84 km / 12 km/h = t

Simplifying the left side, we get:

7 h = t

Therefore, it takes 7 hours to travel 84 km at a speed of 12 km/h.
