Question 1153380:
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 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 151

miles. What is the top running speed of each of these three​ animals?
The jackal can run at how many miles per hour?

CHEETAH          2j
JACKEL            j
ELK               j+11

One hour, total distance of the three, 151 miles.

2h%2Bj%2B%28j%2B11%29=151

4j=151-11

4j=140

highlight%28j=35%29----------jackel speed
