Answer:
The answer is 10/21 also known a C
Answer:
Step-by-step explanation:
2(2 color pants)*4(4 colored shirt)*2(2 colored tie)=16
Tree diagram below:
I= Prt
I= 25,000*0.005*6
I=215*6
I=1290
1290 is the interest.
Let speed of the boat in still water = x miles per hour
Let speed of the current = y miles per hour
When water and current both flow in same direction then effective speed will be sum of both speeds that is (x+y)
now plug the given values in formula speed=distance/time
we get equation:
(x+y)=160/8
or x+y=20...(i)
When water and current both flow in opposite direction then effective speed will be difference of both speeds that is (x-y)
now plug the given values in formula speed=distance/time
we get equation:
(x-y)=160/40
or x-y=4
or x=4+y...(ii)
plug value of x into (i)
4+y+y=20
4+2y=20
2y=16
y=8
plug value of y into (ii)
x=4+8=12
Hence final answer is given by:
Speed of the boat in still water = 12 miles per hour
Speed of the current = 8 miles per hour
You do 9=5y-6. And then solve for y. It’s is 3.
