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.
Answer:
cases does he hear per hour.
Step-by-step explanation:
Unit rate is expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.
Given: Jerry hears five cases every two and three eights hours.
⇒ 5 cases for every hours
or we can write this as;
For every hours he hears 5 cases.
Unit rate per hour = cases.
Therefore, he hears cases per hour at this constant rate.
