9. **Problem:** A whale swims at a constant speed of 8.0 m/s for 17 s. Calculate the distance traveled by the whale.<br /><br />**Formula:** Distance = Speed × Time<br /><br />**Solution:**<br />* Distance = 8.0 m/s × 17 s<br />* Distance = 136 m<br /><br />**Answer:** The whale travels 136 meters.<br /><br /><br />10. **Problem:** A girl cycles for 30 s at a speed of 4 m/s. Calculate the distance she travels.<br /><br />**Formula:** Distance = Speed × Time<br /><br />**Solution:**<br />* Distance = 4 m/s × 30 s<br />* Distance = 120 m<br /><br />**Answer:** The girl travels 120 meters.<br />
