14
First multiply
1 and 3/4 by 8 and then you got your answer
The speed of motorboat is 36 kmph and speed of current is 4 kmph.
Step-by-step explanation:
Distance covered in 4 hours = 160 km
Time took on return trip = 5 hours
Let,
x represent the speed of boat.
y represent the speed of current.
Combined speed of boat and current when in same direction = x+y
Speed of boat and current when travelling against = x-y
Distance = Speed * Time
Speed = 
x+y = 
x+y = 40 Eqn 1
x-y = 
x-y = 32 Eqn 2
Adding Eqn 1 and Eqn 2

Dividing both sides by 2

Putting x=36 in Eqn 1

The speed of motorboat is 36 kmph and speed of current is 4 kmph.

Answer: B or 2 is the answer!
Step-by-step explanation: hope everyone does great on their test i have the same one lolz :)
1) 2:5 ratio
This is a fairly simple process, you count how many of each and then put them in order the way the question asks.
So there are 5 cans and 2 bottles. The question asks "bottles to cans" so the correct answer HAS to be 2:5, NOT 5:2.
2) 3:1
There is 1 spoon and 3 forks. The question asks "forks to spoons" so the correct answer HAS to be 3:1, NOT 1:3
