Answer:

92km

Step-by-step explanation:

According to this question, Lily took 6 hours to complete a journey at an average speed of 58km/h.

Using:

Speed (m/s) = distance (m) /time (s)

58 = d/6

d = 348km

The distance to complete the journey is 348km.

- For the first 4 hours, she travelled at an average speed of 64 km/h.

That is, 64 = d/4

d = 4 × 64

d = 256km

She travelled a distance of 256km in the first four hours.

Hence, the distance for the rest of the journey will be:

348km - 256km

= 92km
