We have 2 journeys , one to school and one to home.
We already have the distance travelled in the first journey .
To find the distance of the second one , we need to find out the time .

Because ,
D= Time x speed
Since have the distance of the first journey , we can find the the time of the second journey .

Using the formula:
Time= D/S

To find the total time :

First:
Convert 20 minutes to hours : 20/60= 0.33 hrs
And add it to 3 (3hrs) = 3+0.33= 3.33hrs

This is our total time .


Second:
To find the time of the first journey , we divide:
130/95= 1.36hrs
(D/S)=T

Since we need the time of the second half, we subtract the time of the first half from the total time travelled:
3.33-1.36= 1.97hrs

And that’s how we found out the time of the second journey (again to find distance).

Now , the last step is to workout the distance travelled at the second journey.
We have the time = 1.97 hrs and the speed = 65 km/h
D=T x S
1.97 x 65= 128.05 km

And that’s your answer.

aksik [14]
In solids, particles or atom are very closely arranged compared to gasses. When these particles are arranged in such proximity, vibrations from sound are very easily transmitted from one particle to another in the solid. Hence, the sound vibrations can travel through the solid medium more quickly than through a gas medium.
Speed of sound also depends on its frequency and the wavelength.
