Answer:

t = 6 hours

Step-by-step explanation:

Given that,

Average speed, v = 7 km/h

Distance, d = 42 km

We need to find the time taken to complete the course. The average speed is given by :

[tex]v=\dfrac{d}{t}\\\\or\\\\t=\dfrac{d}{v}\\\\t=\dfrac{42\ km}{7\ km/h}\\\\t=6\ h[/tex]

So, the time taken to complete the course is 6 hours.
