Question

A)S=121 km v=11 km/h b) S=990 m v=11 km/h

Answer 1

Ответ:

t= 121÷11= 11 h

990m = 0,99 km

t= 0,99÷11= 0,09 h

Answer 2

It looks like you've provided two scenarios, each with a given distance (S) and velocity (v). You may be looking to calculate the time (t) it takes to travel the given distance at the specified velocity. The formula to calculate time (t) is:

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

Let's plug in the values for each scenario and calculate the time for each one.

Scenario A: Given $S = 121$ km and $v = 11$ km/h

$t_A = \frac{121 \, \text{km}}{11 \, \text{km/h}}$

$t_A \approx 11 \, \text{hours}$

Scenario B: Given $S = 990$ m (0.99 km) and $v = 11$ km/h

$t_B = \frac{0.99 \, \text{km}}{11 \, \text{km/h}}$

$t_B \approx 0.09 \, \text{hours}$

However, the result is in hours, and it's more common to express time in minutes, so let's convert hours to minutes.

$t_B \approx 0.09 \, \text{hours} \times 60 \, \text{minutes/hour}$

$t_B \approx 5.4 \, \text{minutes}$

So, in Scenario A, it would take approximately 11 hours to travel 121 km at a velocity of 11 km/h, and in Scenario B, it would take approximately 5.4 minutes to travel 990 m at the same velocity.
