To find out how many men are in the race, we can start by using the following formula:
Number of men = percentage of men x total number of runners
We are given that 20% of the runners are men, so the percentage of men is 0.2. The total number of runners is 360.
Number of men = 0.2 x 360
Number of men = 72
Therefore, there are 72 men in the race.
