Answer 2

Answer:

Step-by-step explanation:

Given that,

person walks 100 m in first 50 seconds, 80 m in next 30 seconds, 45 m in last 35 seconds

we need to find,

average speed of Person

Average speed is defined as the total distance covered by any body divided by total time taken to cover it.

Average speed = total distance covered / total time taken

average speed = ( 100 + 80 + 45 ) / ( 50 + 30 + 35 )

average speed = ( 225 ) / ( 115 )

average speed = 1.95 m/s

therefore,

Average speed of person is 1.95 m/s .
