The top running speed of a cheetah is double the top running speed of a jackal. The top running speed of an elk is 11 miles per
1 answer:
Answer:
The speed of Jackal is 35 miles per hour.
The speed of Cheetah is 70 miles per hour.
The speed of Elk is 46 miles per hour.
Step-by-step explanation:
Consider the provided information.
Let J represents the top speed of jackal.
The top running speed of a cheetah is double the top running speed of a Jackal.
This can be written as:
Cheetah = 2J
The top running speed of an elk is 11 miles per hour faster than that of a Jackal.
Elk = J + 11
If each of these three animals could run at top speed for an hour (which, of course, is not possible), they could run a combined distance of 151.
This can be written as:
Hence, the speed of Jackal is 35 miles per hour.
The speed of Cheetah is 2J = 2×35 = 70
Hence, the speed of Cheetah is 70 miles per hour.
The speed of Elk is J + 11 = 35+11 = 46
The speed of Elk is 46 miles per hour.

Step-by-step explanation:
The problem could be simplified as following:
Given:
The radius of a circle O is 26 feet.
Solve for:
The length of arc on circle O that measures 13 radians
Solution:
Step 1: Let's find out the correct formula to apply:
The formula to calculate the length of an arc measuring x radians on a circle with radius r feet is:
L = r*x
Step 2: Let's put the data into formula to work out the length L of arc:
L = 26*13 = 338 (ft)
=> The distance that a horse does on the outer edge travel when the carousel rotates through 13 radians: L = 338 (ft)
