Answer:
Step-by-step explanation:
b and c are the speeds of the boat in stool water, and current, respectively.
Going with the current, the boat travels b+c=16 km/h.
Going against the current, the boat travels b-c=6 km/h
add the equations together
b+c = 16
b-c = 6
—————
2b = 22
b = 11
c = 16-b = 5
Answer:
12:30 pm
Step-by-step explanation:
8:30 am pond is empty
10:30 am pound is 1,400 gallons full
time? pound is 2,800 gallons full
from 8:30 to 10:30 are 2 hours so the rate of filling up is
1,400 gallons in 2 hours
to have a whole pond filled we need another 2 hours because
in another 2 hours will have another 1,400 gallons so a pound full. 8:30 am + 2hours = 12:30 pm
8:30 am pond is empty
10:30 am pound is 1,400 gallons full
12:30 pm pound is 2,800 gallons full.
I want to say that shows a decreasing interval, since it is going downwards.
Turn the 50 into a fraction (50/1) then cross multiply the fractions after that turn it into a equivalent fraction and you you get your answer
