Explanation:
Given
Total Distance = 720km
Average Speed = 90km/h
Average Speed (285km) = 95km/h
Required
Determine the average speed for the rest of the journey
First we need to determine the time taken to complete the journey using
Make Time the subject of formula
Next, we determine the time taken to complete 285km of the journey using
Make Time the subject of formula
The difference between these calculated times is the time taken to complete the rest of the journey
Also, we need to calculate the distance of the rest of the journey
The average speed can then be calculated;
<em>Hence, the average speed of the rest of the journey is 87km/h</em>
