Answer:
57.6 km per hr
Step-by-step explanation:
Let us assume the horizontal distance between the ship is constant = x
= 70 Km
The ship A sails south at 40km/h is denoted as 40t
The Ship B sails north at 20 km/h is denoted as 20t
Now the vertical distance separating the two ships is
= 20t + 40t
= 60t
And, the Distance between the ship is changing
As x is constant
Now differentiating
The distance between two ships is at 4
So,
vertical distance is
= 240
And, the horizontal distance is 70
So, the distance between the ships is 57.6 km per hr
Answer:
0.43 liters = 430 milliliters
Step-by-step explanation:
There are 1000 milliliters in each liter so all you have to do is multiply 0.43 by 1000. :)
Answer:
2
Step-by-step explanation:
We can find the slope using the formula
m = ( y2-y1)/(x2-x1)
= ( 5-1)/( -1 - -3)
= ( 5-1)/( -1+3)
= 4/2
= 2
