Question
Julius visits his friend who lives in another city.The car ride takes 8 hours when he is driving at an average speed of 30 km/h.What would be the average speed of the car if the same journey took only two hours?
Solution
To solve this problem, we first need to find out the total distance of the journey. We can do this by multiplying the time of the journey by the speed of the car.
Step 1: Calculate the distance of the journey Distance = Speed x Time Distance = 30 km/h x 8 hours = 240 km
Now we know that the total distance of the journey is 240 km.
Step 2: Calculate the new average speed If the same journey took only two hours, we can find the new average speed by dividing the total distance by the new time.
Average Speed = Distance / Time Average Speed = 240 km / 2 hours = 120 km/h
So, if the same journey took only two hours, the average speed of the car would be 120 km/h.
