Question

A person swims 100m in the first 40 sec, 90m in the next 40 sec and 55m in the last 20 sec. What is the average speed?​

Answer 1

Answer:

Total distance = 100+ 80+45 m = 225m

Total time = 40+40+20s = 100s

Average speed = total distance /total time

Average speed = 225m/100s

Average speed = 2.25m/s

Hope this helps!!
