18% because take the first digits of each number and put them together lol
X=37/5
or 7.4 in decimal form
Answer:
18.87 km/hr
Step-by-step explanation:
First boat is heading North with a speed of 10 km/hr.
Second boat is heading West with a speed of 16 km/hr.
Time for which they move = 2.5 hours
To find:
The speed at which the distance is increasing between the two boats.
Solution:
Let the situation be represented by the attached diagram.
Their initial position is represented by point O from where they move towards point A and point B respectively.
We can use Pythagorean Theorem to find the distance AB.
AB is the hypotenuse of the right angled .
According to Pythagorean theorem:
The speed at which distance is increasing between the two boats is given as:
The perimeter of a square with a side measurement of 6 inches is equal to 24 inches.
