To determine how long it will take the athlete to run around the track fifteen times, we first need to calculate the total time for one round and then multiply it by fifteen.
Given:
- Time to run one round = 58 seconds
Now, we calculate the total time for fifteen rounds:
\[ \text{Total time for 15 rounds} = 15 \times 58 \text{ seconds} \]
Calculating that:
\[ 15 \times 58 = 870 \text{ seconds} \]
Next, we convert the total seconds into minutes. Since there are 60 seconds in a minute, we divide the total seconds by 60:
\[ \text{Total time in minutes} = \frac{870}{60} \]
Calculating that gives:
\[ \frac{870}{60} = 14.5 \text{ minutes} \]
Thus, it will take the athlete 14.5 minutes to run around the track fifteen times.
