speed of 3 ms-1 ,along a straight track .The average speed of the man is​

Answer 1

Answer:

A man walks for 1 "minute" at a speed of 1 m s^(-1) and then runs for 1 min at a speed of 3 ms ^(-1) along straight track, Hence, t1=1min=60s,v1=1ms-1,t2=1min=60s,v2=3ms-1

Answer 2

A man walks for 1 "minute" at a speed of 1 m s^(-1) and then runs for 1 min at a speed of 3 ms ^(-1) along straight track, What is the average speed of the man? Hence, t1=1min=60s,v1=1ms-1,t2=1min=60s,v2=3ms-1.
