Answer:
Speed of river's current = 5 mph
Step-by-step explanation:
Let 'd' be the distance covered
Let x be the speed of the rivers current
Speed upstream = 15-x
speed downstream = 15+x
Time = distance / speed
time upstream = 
time downstream = 
the ferry trip upstream takes twice as long as its return trip downstream
= 
divide both sides by d
= 
cross multiply
Add 2x on both sideds
subtract 15 from both sides and divide by 3
x=5
Speed of river's current = 5 mph
It looks floppy but you said you need this fast so yeah
Answer:
Number of people employed this year = 373
Step-by-step explanation:
Let the number of employees this year = x
These employees were decreased by 4% then the remaining number of employees this year = x - (4% of x)
= x - 0.04x
= 0.96x
If last year number of people employed were 389 then the number of people employed this year = 0.96×389
= 373.44
When rounded to whole number, number of people employed this year = 373.
