Question

Calcula el tiempo que tarda en llegar a la Tierra la luz del sol si viaja a 300.000 km/s sabiendo que la distancia del sol a la tierra es de 150.000.000 km. Exprésalo en minutos

Answer 1

Calculate the time it takes for sunlight to reach Earth if it travels at 300,000 km / s, knowing that the distance from the sun to the earth is 150,000,000 km. Express it in minutes

Answer:

8.3min

Explanation:

Given parameters:

Speed of sunlight  = 300000km/s

Distance of sun and earth  = 150000000km

Unknown:

Time in minutes  = ?

Solution:

To solve this problem;

     Speed  = $\frac{distance }{time}$  

 Time = $\frac{distance}{speed}$  

Now insert the parameters and find the speed;

  Time  = $\frac{150000000}{300000}$   = 500s

Now;

  60s makes 1 minute

 500s will give   $\frac{500}{60}$   = 8.3min
