Answer: A full game of soccer lasts 90 minutes.
Step-by-step explanation: If 60% of the time has gone by and this is equivalent to 54 minutes having passed by, then we can use a proportion to find out how many minutes are in a full game of soccer:
60% / 100% = x / 90 minutes
We can cross-multiply to solve for x:
100% * x = 60% * 90 minutes
x = (60/100) * 90 minutes
x = 54 minutes
Therefore, there are 90 minutes in a full game of soccer.
Hope this helps, and have a great day!
