Let the rate of the current be x mph and rate of the boat in still water be y mph.
So the relative speed of the boat with the current ( downstream) = y + x and against the current (upstream) it = y - x.
Then , using speed = distance / time:-
y - x = 120/3 = 40
y + x = 120/2 = 60
Adding the 2 equations:-
2y = 100
y = 50
And substituting in the frst equation:-
50 - x = 40
x = 10
Answer:- Rate of boat in still water = 50 mph and rate of the current = 10 mph.
Answer:
Step-by-step explanation:
Your answer is 9.
53 x 2 = 106
106 + 20 = 126
126 / 14 = 9 !
The answer is g=13 I hope this helped
5⁰ = 1
5¹ = 5
5² = 25
5³ = 125
5⁴ = 625
5⁵ = 3125
Answer:
The us based motorcycle manufacturer says that it expects to build 140,000 motorcycles this year up from 126,000 last year.
This means the increased production is
144,000 - 126,000 = 18,000
The percentage change in production can
be found using the formula as listed below
PERCENTAGE INCREASE = change / initial × 100
Substitute the values we get
18,000/126,000 × 100
14.28 = percentage increase
