Joe has travelled a distance of 60 km from town A to town B in 3 hrs. And then another 40 km from town B to town C in 2 hrs. Find the average speed for his entire journey.
20 km/hr
We have known that Average speed =Total distance coveredTotal time taken
Here, the total distance which he has covered is = 60 km + 40 km = 100 km
And, the total time taken = 3 hrs + 2 hrs = 5 hrs
So, Average speed = 100 km/ 5 hrs = 20 km/hr
