Let s be the speed of the boat in still water.
Let c be the speed of the current.
s - c = 48/6 = 8
s + c = 48/4 = 12
Adding the two equations, we get:
2s = 20
s = 10
The answer is 10 miles per hour.
Answer:
a. Of all the students,

are boys without brown hair.
Answer :
Option B
Step by step explanation :
As we can see in figure, Triangle is right angled at A
In ∆ABC
By Pythagoras theorem,
BC² = AC² + AB²
=> BC² = (3)² + (4)²
=> BC² = 9 + 16
=> BC² = 25
=> BC = 5 cm
We know,
=
Here,
base = AC = 3cm
height = AB = 4cm
=>
=
=> 
=> 
As BC = DE
And then BD = EC
it shows the property of rectangle
So BD = 6 cm
Now,

=> Area of rectangle = 6cm x 5cm
=> 
Now,
Area of the figure = Area of rectangle + Area of triangle
=> Area of the figure = 30cm² + 6cm²
=> 
Therefore, <u>option B</u> is the correct answer for this question.
