Answer:

<em>15.4 </em>

Step-by-step explanation:

\frac{u}{4} = tan51.3° ⇒ u = 4tan51.3° ≈ 5

\frac{4}{v} = cos51.3° ⇒ v = \frac{4}{cos51.3} ≈ 6.4

<em>P </em>≈ 4 + 5 + 6.4 = <em>15.4</em>

vesna_86 [32]

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

t=\frac{X}{V}

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

t=\frac{10}{5} =2h

swimming

x=1mile

v=3milles/h

t=\frac{1}{3} =0.3h

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
