Answer:
To find the average speed of their combined trips, we can use the formula:
Average speed = Total distance ÷ Total time
To find the total distance, we simply add up the distances each person travelled:
Total distance = 36 + 48 + 56 = 140 km
To find the total time, we add up the times each person travelled:
Total time = 8 + 10 + 12 = 30 hours
Now we can plug in these values to the formula for average speed:
Average speed = 140 km ÷ 30 hours = 4.67 km/h
Therefore, the average speed of their combined trips is 4.67 kilometers per hour.
