Answer 2

А) 115*15=1725 м или 1км 725м
б) 285/15=19 км/ч

Answer 3

Calculation of Distance (s) when v = 115 km/h and t = 15 h

To calculate the distance (s) traveled when the velocity (v) is 115 km/h and the time (t) is 15 hours, we can use the formula s = vt, where s represents the distance, v represents the velocity, and t represents the time.

Substituting the given values into the formula, we have:

s = v * t s = 115 km/h * 15 h

To find the distance, we multiply the velocity by the time:

s = 1725 km

Therefore, when the velocity is 115 km/h and the time is 15 hours, the distance traveled is 1725 km.

Calculation of Velocity (v) when s = 285 m and t = 15 min

To calculate the velocity (v) when the distance (s) is 285 m and the time (t) is 15 minutes, we can rearrange the formula s = vt to solve for v.

Dividing both sides of the equation by t, we have:

v = s / t v = 285 m / 15 min

To find the velocity, we divide the distance by the time:

v = 19 m/min

However, it is important to note that the units for velocity should be consistent. In this case, the distance is given in meters (m) and the time is given in minutes (min). To convert the velocity to a more common unit, such as kilometers per hour (km/h), we need to convert the distance and time accordingly.

Converting the distance from meters to kilometers:

285 m = 0.285 km

Converting the time from minutes to hours:

15 min = 0.25 h

Now, we can calculate the velocity:

v = 0.285 km / 0.25 h v = 1.14 km/h

Therefore, when the distance is 285 m and the time is 15 minutes, the velocity is approximately 1.14 km/h.
