Calculate the average speed of your different vehicle from your home to nearst library/town
Answers
Answer:
Here is the scenario, I leave home and drive to the cafe which is 3 km away in 1 hour. I take breakfast for 30 minutes. From the cafe, I drive to my friends house in 45 minutes which is 2.5 km from the cafe. I pick my friend and we head for the library which is 4.5 km away from my friend's house. We get to the library after 1 hr and 45 minutes
The average speed for this whole journey from my home to the library is 2.5 km/hr
Explanation:
Average speed formula:
Average speed = total distance traveled / total time taken
Let's calculate the total distance
Home to cafe = 3km
Cafe to friend's house = 2.5 km
Friends house to library = 4.5km
Total distance = 3 km + 2.5 km + 4.5 km = 10 km
Let's now get the total time taken:
Home to cafe = 1 hour
In the Cafe = 30 minutes = 0.5 hours
Cafe to friends home = 45 minutes = 0.75 hours
Friend's home to library 1 hour 45 minutes = 1.75 hours
Total time taken = 1 hr + 0.5 hr + 0.75hr + 1.75hrs = 4 hours
Therefore total distance is 10km and total time is 4 hours
Average speed = total distance / total time
= 10 km / 4 hours
= 2.5 km/hr
Therefore the average speed from my home to the library is 2.5km/hr
