Complementary I’m sure but I could be wrong
All you have to do is cancel the x 4/11
Hey!!
here is your answer >>>>
If there are 8 students, and who have 3/4 the cake to share equally, we will have to divide 3/4 with 8.
which is( 3/4)/(8)
Now, we will have to take a reciprocal, we get,
(3/4)(1/8)
which is 3/32
which is
Each student gets, 3/32 of the cake!
Hope my answer helps!
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
