The current in a river is 1.0 meters/second. Britney swims 300 meters against the current. If she normally swims with a speed of 2.0 meters/second in still water, how long does it take her to complete the trip? A.
100 seconds
B.
200 seconds
C.
400 seconds
D.
300 seconds

D) 300 seconds

Step-by-step explanation:

if the river is traveling 1 m/s and Britney is traveling 2 m/s, then half of her speed would be canceled out, resulting in her only traveling 1 m/s taking her 300 seconds or 5 minutes to complete the trip.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

saving = more money

step-by-step explanation:
