Final answer:
Kayaker A will arrive at the mutual friend first, with a time difference of 22.22 s.
Step-by-step explanation:
To determine which kayaker will arrive at the mutual friend first and by how much time, we need to compare their travel times. Let's calculate the travel times for kayakers A and B:
- Kayaker A's travel time = distance/speed = 150.0 m/2.25 m/s = 66.67 s
- Kayaker B's travel time = distance/speed = 200.0 m/2.25 m/s = 88.89 s
Kayaker A will arrive at the mutual friend's location first, with a time difference of 88.89 s - 66.67 s = 22.22 s
