Answer:
rowboat C traveled the fastest
Explanation:
divide the meters by the amount of seconds for each rowboat
rowboat A:
= 40 meters in 10 seconds
rowboat B:
= 30 meters in 10 seconds
rowboat C:
= 60 meters in 10 seconds
rowboat D:
= 50 meters in 10 seconds
then you get the boat that traveled the most in 10 seconds which is rowboat C
