Question

a person runs hundred metre in the first 50 second 80 in the next 30 second and 45 in the last 35 seconds 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!!

Answer 2

Answer:

Thanks for A2A

Let's get down to the question, well it seems you cannot calculate average speed because the time given is not same.

Speed=distance/time

Variable time is not considered in logical sense in calculating average speed although being mathematically correct and legit.

No matter how fast you travel even at the speed of light you cannot calculate average speed in this case.
