289 estimated is 290
7 estimated it 10.
290 times 10 is 2,900
Answer:
0.43 miles
Step-by-step explanation:
Let t be the time it takes Achilles to run the race. Since Achilles runs at a speed of 13 mph, the distance he covers in time t is d = 13t.
Also, by the time Achilles finishes the race, the turtle has already covered a distance, d at a speed of 1 mph in the same time, t. So, d' = 1t = t
Given that when Achilles reaches the finish line, the turtle is 2/5 of a mile behind him, then d - d' = 2/5.
So, 13t - t = 2/5
12t = 2/5
t = 2/5 × 1/12
t = 1/5 × 1/6
t = 1/30 h
So since d = distance from start to finish = distance Achilles covers = 13t,
Substituting t = 1/30 into d, we have
d = 13t
= 13 × 1/30
= 0.43 miles

It'll never happen unless they are running on a globe. You could have those two running forever in a straight line and the cheetah will always be ahead of the lion. The longer they go, the more the distance between them.

Step-by-step explanation:
The triangles are drawn below.
Since, CD is the height to AB, therefore, CD is perpendicular to AB.
Therefore, angles °
Also, is same as .
Therefore, °
Now, triangles ΔCBD and ΔCAD are right angled triangles.
So, for the right angled triangle ΔCAD,
Now, from the figure,
