Question

Gino took 6 hours to complete a journey at an average speed of 65 km /h lorry took 2 hours fewer than Gino to complete the same journey what was lorry me average speed for the whole journey

Answer 1

97.5 km/h

Step-by-step 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.
