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
Alright 3 hours =315 because u add up both miles so per hour they move 105miles closer to each other so now we need to figure out how to get an extra 45 miles

Answer:
f = 1
Step-by-step explanation:
-f + 2 + 4f = 8 - 3f
-f + 4f + 3f = 8 - 2
6f = 6
f = 6/6
f = 1
Hope it helps!!
Answer:
-2
Step-by-step explanation:
you would go to wear your line crosses you y-axis, which is the vertical one
so it crosses at -2
