A total of 600 athletes from different teams compete in a ( 5 mathrm{~km} ) race. The times the 600 athletes took to run the ( 5 mathrm{~km} ) race are shown in the following cumulative frequency graph. There were 400 athletes who took between 22 and ( m ) minutes to complete the ( 5 mathrm{~km} ) race. (d) Find ( m ). [3] The first 150 athletes that completed the race won a prize. (e) Given that an athlete took between 22 and ( m ) minutes to complete the ( 5 mathrm{~km} ) race, calculate the probability that they won a prize. [5]

Step 1
We are told that 400 athletes completed the race in between 22 minutes and \(m\) minutes. We need to find the value of \(m\). Additionally, we are asked to calculate the probability that an athlete who completed the race in between 22 and \(m\) minutes won a Show more…
