A normal heart rate ranges between 60-100 beats per minute. The higher the heart rate is, the faster the blood is pumping through the heart. When exercising a persons heart will be higher because the brain and the muscles in the body are in need of oxygen so the heart needs to pump faster in order to sustain optimal performance.<span />

How much faster does sound travel in the ocean than in the rain forest?
Greeley [361]
Hi there,
Speed of sound in water is approximately 1500 meters per second (the exact speed depends on the depth of water and its density) and the speed of sound in air is approximately 340 meters per second. So sound is almost 4.4 times faster in water than in air. I hope this helped :)
