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
$125-$81.25 =$43.75 so that is how much was saved. Now figure what percentage $43.75 is of $125. so $43.75÷$125=.35 and changing to % the discount is 35%
Well it depends if there was any markings but looking at that picture theres no markings so it cant be measured by any.
This first one where Jeremy is already in 250miles. X is the amount of time.
