Answer:
2 mph
Step-by-step explanation:
time = distance / speed
Let c represent the rate of the current. Then the upstream rate of the boat relative to the shore is (5c -c) = 4c, and the <em>upstream time</em> is ...
... 12/(4c) = 3/c.
Likewise, the downstream rate is (5c +c) = 6c, and the <em>downstream time</em> is ...
... 12/(6c) = 2/c.
The <em>total time</em> is the sum of upstream and downstream times:
... 3/c +2/c = 2.5
... 5/c = 2.5 . . . . . . combine terms
... 5/2.5 = c = 2 . . . multiply by c/2.5
Answer:
is it's right answer is 572
Answer:
Input is the value of w and the function f = 24/w as length x breadth = area of rectangle
If w = 0.5, then f = 24/0.5 = 48cm. So, it is a possible input of the function.
If w = 48, then f = 24/48 = 0.5cm. So, it is a possible input of the function.
If w = 0, then f = 24/0 = 0cm. So, it is not a possible input of the function as it cannot be defined
If w = -6, then f = 24/-6= -4cm. So, it is not a possible input of the function as a length and width can't be negative
If w = 3, then f = 24/3 = 8cm. So, it is a possible input of the function.
Answer:
5m^2 + 15m
Step-by-step explanation:
use distributive property:
5m(m) is 5m^2
5m(3) is 15m
which is 5m^2 + 15m
Answer:
3 1/2 miles
Step-by-step explanation:
because 6 - 2 1/2 = 3 1/2
