Answer:

The speed of the long distance runner is 8km/h

Step-by-step explanation:

In this question, we have a long-distance runner, running at a constant rate and we want to find his speed.

Mathematically,

speed = distance/ Time

From the question, we are told that he passes the 44km mark 3 hours after passing the 23km mark in 2 hours and 30 minutes

what this means is that the total distance he ran was just 44km

Now to the total time, that would be 2 hours 30 minutes + 3 hours = 5hrs 30 minutes or 5.5 hours

The speed is thus = 44km/5.5 hours =

8km/h
