Answer: The number of supervisors are 9 times the number of unicorns.
Step-by-step explanation:
Let the number of supervisors be 'n'.
Let the number of unicorns be 'u'.
According to question, a unicorn daycare center requires there to be 2 supervisors for every 18 unicorns.
So, Mathematically, it is expressed as
so, we established the relationship between the number of supervisors and number of unicorns.
Hence, the number of unicorns are 9 times the number of supervisors.
Let, speed of 1st bicyclist is x.
So, speed of 2nd bicyclist is x-3 .
We know, relative speed when two objects moves towards each other :
Now, distance travelled in 3 hours is (98-2) miles .
So,
Therefore, speed of bikes are 17.5 mph and 14.5 mph.
Hence, this is the required solution.
Answer:
<em>L = 24,873.6 miles</em>
Step-by-step explanation:
<u>Length of the Circumference</u>
Given a circle of radius r, the length of the circumference, or line surrounding the shape is:
The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:
r=7,917.5/2=3,958.75 miles
Assuming a plane flies around the equator at ground level, the distance it would travel is:
L = 24,873.6 miles
