Answer: His friend's speed is 54.2km/hr. Rounded to one decimal place.

Step-by-step explanation:

The speed held by john = 65km/hr

Time = 5 hour.

Since they both follow the same route we calculate the distance first.

Speed = Distance/time

65 = distance/5

Distance = 65 * 5

Distance = 325km.

Now for the speed his friend cover with the same route will have the same distance.

Distance = 325km

Time = 6hours

Speed = ?

Speed = distance / time

Speed = 325/6

Speed = 54.2 km/hr. Rounded to one decimal places.
