Answer:

83.33 km/h (2 d.p.) = 23.15 m/s (2 d.p.)

Step-by-step explanation:


\boxed{\sf Speed=(Distance)/(Time)}

Given values:

  • Distance = 250 km
  • Time = 3 h

Substitute the values into the formula and solve for speed:


\implies \sf Speed=(250\;km)/(3\;h)


\implies \sf Speed=83.33\;km/h\;(2\;d.p.)

If you wish to convert kilometers per hour into meters per second, divide by 3.6:


\implies \sf Speed=(250)/(3) / 3.6=(625)/(27)=23.15\; m/s\;(2\;d.p.)

Hello..! :)

Topic: Uniform Rectilinear Motion.

To calculate the average speed of the car we raise the following data that are.

Data:

  • V = ?
  • D = 250km
  • T = 3hrs

Now, we apply the speed formula.

Formula:

  • V = D/T

Finally we develop the problem, for this we divide distance by time.

Developing:

  • V = 250km / 3h
  • V = 83.33km/h

So the average speed traveled by the car is 83.33 kilometers per hour.

¿Doubts? On the comments. Greetings :D
