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