Answer 1

To find the average speed of the runner, you first need to calculate the total distance covered and the total time taken.

1. Calculate the total distance: \[ \text{Total Distance} = 180 , \text{meters} + 188 , \text{meters} + 190 , \text{meters} = 558 , \text{meters} \]

2. Calculate the total time: \[ \text{Total Time} = 30 , \text{seconds} + 30 , \text{seconds} + 30 , \text{seconds} = 90 , \text{seconds} \]

3. Calculate the average speed: \[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} = \frac{558 , \text{meters}}{90 , \text{seconds}} \approx 6.2 , \text{m/s} \]

Therefore, the average speed of the runner is 6.2 m/s.
