Question

A person swims 100m in the first 40s,80m in the next 40s and 45m in the last 20s . what is the average speed ?

Answer 1

Answer:

Step-by-step explanation:

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!!

Answer 2

Answer

Average speed = Total distance/ Total time

Total distance = 100 + 40 + 45 = 225 m

Total time = 40 + 40 + 20 = 100 s

Average speed = 225/100 = 2.25 m/s
