The average speed = distance/time
Since the jet flies 3600 km in 6 hours, then
The distance = 3600 km
The time = 6 hours
Divide them to find the average speed
[tex]\begin{gathered} A\mathrm{}S=\frac{3600}{6} \\ A\mathrm{}S=600\text{ km/h} \end{gathered}[/tex]The average speed of the jet is 600 km per hour
