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

answer; how far out of place which the object finished relative to the starting location;

inverse v=i*r
