Average speed = total distance travelled / total time taken
Let total time be 2t
This implies that time in first half = t= time in second half
Total distance covered = 30t+45t= 75t
Total time = 2t
Average speed = 75t/2t
= 37.5m/s
Let total time be 2t
This implies that time in first half = t= time in second half
Total distance covered = 30t+45t= 75t
Total time = 2t
Average speed = 75t/2t
= 37.5m/s
