A man jogs halfway to his destination at 8 km/hr and walks the rest of the way at 6 km/hr. What is his average speed for the entire trip?
Added by Anthony R.
Step 1
Let's assume the total distance to the destination is 2D (for simplicity, as he jogs halfway). So, the distance he jogs is D and the distance he walks is also D. The time he spends jogging is D/8 and the time he spends walking is D/6. So, the total time spent Show more…
