8 cars are in race and different timing for each car then find avg speed.
41.25 km/hr
explanation or that question
To find the average speed of the cars in the race, we need to know the distance covered by each car and the time taken by each car to cover that distance.
If we are given the different timings for each car, we can calculate the average speed using the following formula:
Average Speed = Total Distance / Total Time
To find the average speed, follow these steps:
1. Determine the distance covered by each car. This distance can be measured in miles, kilometers, or any other unit of distance.
2. Note down the time taken by each car. The time should be consistent, such as minutes, hours, or seconds.
3. Add up all the distances covered by the cars to get the total distance.
4. Add up all the time taken by the cars to get the total time.
5. Divide the total distance by the total time to calculate the average speed.
Let's say the timings of the 8 cars are as follows:
Car 1: 10 minutes
Car 2: 15 minutes
Car 3: 12 minutes
Car 4: 20 minutes
Car 5: 18 minutes
Car 6: 14 minutes
Car 7: 16 minutes
Car 8: 13 minutes
Assuming all the cars covered the same distance, we can calculate the average speed as follows:
Total Distance = Distance covered by each car x Number of cars
Total Time = Sum of all the timings
For simplicity, let's assume that each car covered a distance of 100 km.
Total Distance = 100 km x 8 = 800 km
Total Time = 10 minutes + 15 minutes + 12 minutes + 20 minutes + 18 minutes + 14 minutes + 16 minutes + 13 minutes = 118 minutes
Now, let's convert the total time to hours by dividing it by 60:
Total Time in Hours = 118 minutes / 60 minutes/hour = 1.97 hours (rounded to two decimal places)
Finally, we can calculate the average speed:
Average Speed = Total Distance / Total Time in Hours
Average Speed = 800 km / 1.97 hours = 405.08 km/h (rounded to two decimal places)
Therefore, the average speed of the 8 cars in the race is approximately 405.08 km/h.
