Answer 2

Answer:

Average time is 0.6 min.

Explanation:

Average of some data is total sum of each data divided by total no.of data (time) in this case.

Here, waiting time is the time of the event occuring

∴Average of a event   = $\frac{time of event}{total time}$

∴Average waiting time=$\frac{Time .spent .for . waiting}{Total .time .of .one cycle .of .the .traffic }$

∴average waiting time = $\frac{3min}{5min}$

∴Average time a person waits is 0.6 min.
