29. Write each speed in metres per second. a) The dolphin can swim at a top speed of 60km/h b) The polar bear can run at a top speed of 40km/h

**a) Dolphin:**<br /><br />* **Conversion:** We need to convert kilometers to meters and hours to seconds.<br /> * 1 km = 1000 meters<br /> * 1 hour = 60 minutes<br /> * 1 minute = 60 seconds<br /> * Therefore, 1 hour = 60 * 60 = 3600 seconds<br /><br />* **Calculation:**<br /> (60 km/h) * (1000 m/1 km) * (1 h/3600 s) = 16.67 m/s (approximately)<br /><br />**Answer:** The dolphin can swim at a top speed of approximately 16.67 meters per second.<br /><br /><br />**b) Polar Bear:**<br /><br />* **Conversion:** We'll use the same conversion factors as above.<br /><br />* **Calculation:**<br /> (40 km/h) * (1000 m/1 km) * (1 h/3600 s) = 11.11 m/s (approximately)<br /><br />**Answer:** The polar bear can run at a top speed of approximately 11.11 meters per second.<br />
