Remember P.E.M.D.A.S to be able to solve  the equations. We'll be using the E (exponents) and M (Multipliction)

SOLVING...

1. 2.5 x 10^4

Solve Exponent... 10^4 = 10000

Multiply... 2.5 x 10000 = 25000

2. 3.4 x 10^4

Solve Exponent... 10^4 = 10000

Multiply... 3.4 x 10000 = 34000

25000 and 34000 are your answers

A woman is standing at the edge of a slow-moving river which is one mile wide, and she wishes to return to her campground on the
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
