Answer:
the best option would be to swim
Step-by-step explanation:
Hello! To solve this problem we must follow the following steps.
1. remember the concept of uniform motion with constant speed, which establishes the following equation
where
t=time
x=distance
V=speed
2. Calculate the time it takes to swim and calculate the time it takes to walk
walking:
x=10mile
v=5milles/h
swimming
x=1mile
v=3milles/h
3. Compare both results and choose the one with the least time.
as you can see it takes less time swimming, so this would be the best way
