Answer:
The competition took 12.5 minutes.
Step-by-step explanation:
Let the time taken by Achilles to complete the competition is h hours.
Now, Achilles runs at a speed of 13 mph while the Turtle moves at a speed of 1 mph.
So, the competition was 13h miles long.
Now, Turtle will take h hours to complete h miles of the competition.
Now, given that (13h - h) = 2.5
⇒ 12h = 2.5
⇒ h = 0.208 hours.
⇒ h = 12.5 minutes.
Therefore, the competition took 12.5 minutes. (Answer)
90 minutes = 1.5 hours.
Divide total miles driven by the time to find how many miles are driven in 1 hour:
250 miles / 1.5 hours = 166 2/3 miles per hour.
Multiply the miles driven in one hour by 6 hours:
166 2/3 x 6 = 1000 miles
