Final answer:
To represent all the possible finishing times of the other participants in the race, an inequality x ≥ 150 can be used. Choose a solution from the options that is greater than or equal to 150 minutes.
Step-by-step explanation:
In order to represent all the possible finishing times of the other participants in the race, we can use an inequality. Let's assume x represents the finishing time in minutes. Since we are looking for all the possible times, we want to include both numbers that are equal to or greater than the winning time. Therefore, the inequality would be x ≥ 150.
To choose a solution from the options, look for a time in minutes that is greater than or equal to 150. For example, if one of the options is 145 minutes, that would not be a valid solution since it is less than the winning time.
