Answer:
No, it is not a representative sample
Step-by-step explanation:
The sampling technique used above is more of a random sampling than a representative sampling. Reason is that;
A representative sample is referred to as a group or set selected from a larger population that satisfactorily represent the population in study in accordance to whatever criteria is under study.
The criteria could be age, sex, class, etc.
Another reason why it can't be considered as a representative sample is that, using representative sampling makes sure that all relevant types of people are included in your sample and that the right mix of people are interviewed.
In the question above, anybody can submit his or choice and number of submissions is not limited.

3/10=18/60
60 represents the hour
18 represents time spent warming up and cooling down.
