The top running speed of a cheetah is double the top running speed of a jackal. the top running speed of an elk is 9 miles per hour faster than that of a jackal. 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 133 miles. what is the top running speed of each of these three animals?

Cheetah: 62 miles per hour.

Elk: 40 miles per hour.

Jackal: 31 miles per hour.

Step-by-step explanation:

Let be "c" the top running speed of the cheetah, "j" the the top running speed  of the jackal and "e" the top running speed of the elk.

Based on the exercise, we know that:

Since they they could run a combined distance of 133 miles in an hour, we can write the following expression:

Substituting and into the expression and solving for "j", we get:

Finally, we must substitute the value of "j" into   and . Then:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
