Answer:
The rate of the current is 2 miles per hour.
Step-by-step explanation:
Let us assume that the rate of the river is v miles per hour.
The speed of the boat is 12 miles per hour.
Let us assume also that the boat can go 21 miles in t hours in the downstream and 15 miles upstream at the same time i.e. t hours.
So, from the condition given we can write that
......... (1), and
......... (2)
Now, adding those two equations we get
⇒
hours
Now, from equation (1), we get,
⇒ v = 2 miles per hour
Therefore, the rate of the current is 2 miles per hour. (Answer)
I’m pretty sure it is B or C
Answer:
Sin 29° 32' = Cos 60° 28'
Step-by-step explanation:
Here in this problem, we have to write Sin 29° 32' in terms of its co-function.
We know that co-function of Sin Ф = Cos ( 90° - Ф ).
Therefore, we have to find a complementary angle of 29° 32'.
So, ( 90° - 29° 32' ) = 60° 28'
Therefore, Sin 29° 32' = Cos 60° 28' ( Answer )
