Question

help needed fast

Answer 1

Heart Rate and Physical Fitness
Jason is on the track team. He runs almost every day, but his friend Caleb hardly ever exercises. Jason and Caleb decide to ride their bikes together to the store. After riding up a particularly steep hill, Caleb notices that his heart is beating extremely fast. However, Jason's heart is still beating at a relatively slow pace. Jason and Caleb wonder why their heart rates are so different after biking up the hill. Caleb thinks that Jason's heart is probably beating more slowly because Jason exercises more often and is in better physical shape. The two boys decide to test Caleb's idea.



What observation did Caleb make?

Answer 2

Caleb observed that his heart was beating extremely fast after biking up the steep hill, while Jason's heart was still beating at a relatively slow pace.
