Distance between Bholu’s and Golu’s house is \(9\ km\). Bholu has to attend Golu’s birthday party at \(7\ o’clock\). He started from his home at \(6\ o’clock\) on his bicycle and covered a distance of \(6\ km\) in \(40\ minutes\). At that point he met Chintu and he spoke to him for \(5\ minutes\) and reached Golu’s birthday party at \(7\ o’clock\). With what speed did he cover the second part of the journey? Calculate his average speed for the entire journey.
 
Distance left to reach Golu's house \(=\)
 
On converting minutes to hour, we get the time as .
 
Speed travelled by Golu in the second part \(=\)
 
Average speed is the  covered divided by the . Hence, on substituting the values, we get .
