(28 : 100) *6 = 1.68 (tax)
28 + 1.68 = 29.68 (total cost)
Answer: a=8 and b=1
Step-by-step explanation:
If x represents the paddling speed, and y represents the speed of the current.
Then Relative speed in upstream =x-y
Relative time in downstream=x-y
When she paddles upstream then distance covered by her=
⇒8=(x-y)2 or 2(x-y)=8
Thus we get, a=1
When she paddles downstream then distance covered by her=
⇒8=(x+y)1 or 1(x+y)=8
Thus we get b=1
Step-by-step explanation:
14 : 10 : 4
Divide it by 2
7 : 5 : 2
This is the simplest form because it cannot be divided further
