Answer:
97.5 km/h
Explanation:
The time taken by gino = 6 hours
Speed of Gino = 65 km/h
The expression for distance is :-
Distance = Speed x Time
So, The distance covered by Gino = 65 km/h x 6 hrs = 390 km
The same distance is covered by Lorry.
Time taken by Lorry is 2 hrs fewer than Gino = 4 hours
Speed = Distance/Time = 390 km/4 h = 97.5 km/h
97.5 km/h is the average speed of Lorry for the whole journey.
