Answer:
5 or 6
Step-by-step explanation:
So I did it in a different way than shown in rsm classes. I said that the speed was x-2 and x.
then I said the distance was 6 and 15. If the time taken was 1 hour more, then we can come up with this equation:
Since the time is 6/x-2 or 15/x
15/x-6/x-2=1
multiply everything to get a common denominator then cancel it out to get
(15x-30)-6x=x^2-2x
11x-30=x^2
x^2-11x+30=0
(x-5)(x-6) is factored form.
so x=5 or x=6. this means that the speed of the boat is either 5km/h or 6 km/h

Answer:
<h2>The answer is 615 m²</h2>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius
From the question
r = 14 m
π = 3.14
The area of the circle is
A = 3.14 × ( 14 ) ²
= 3.14 × 196
= 615.44
We have the final answer as
<h3>615 m² to the nearest whole number</h3>
Hope this helps you
