Answer:
=26.92 m/s
Step-by-step explanation:
Speed is calculated as a ratio of the total distance covered ( It is directionless) to the total time taken to cover the distance.
Average speed= total distance/total time
=x/t
Total distance from the question= 3500m
Total time taken to cover the above distance = 2×60 +10=130 Seconds
Therefore, average speed= 3500m/130 s
=26.92 m/s
