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.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
