Answer:
Explanation:
Here, we are asked to calculate the average speed in km/minute.
As we know that,
Here,
→ Total distance = 10 km + 10 km
→ Total distance = 20 km
→ Total time = 8 minutes + 2 minutes
→ Total time = 10 minutes
Substitute the values in the formula of average speed,
→ Average speed = Total distance ÷ Total time taken
→ Average speed = 20km ÷ 10 minutes
