Lily took 6 hours to complete a journey at an average speed of 58 km/h. For the first 4 hours, she travelled at an average speed of 64 km/h. What was the distance for the rest of the journey?

92km

Explanation:

Given parameters:

Duration of the journey  = 6hrs

Average speed  = 58km/hr

  Now, let us find the total distance of the journey;

 Distance  = Speed x time

  Distance  = 58 x 6   = 348km

So;

 Average speed for the first 4hrs  = 64km/hr

                                               Time  = 4hrs

     Distance  = 64 x 4 = 256km

For the rest of the journey, the student will cover;

                               = 348km  - 256km

                               =  92km

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
