John trains for ultramarathons. He starts only able to run 8 hours straight but eventually increases that by 75%. He also increases his speed of 8 mph by 4 mph. How far can he run now?
Thoughts? Step-by-step reasoning:
User
He increases the time he can run by 8 * .75 = 6 hours. So he can now run 8 + 6 = 14 hours. His speed is now 8 + 4 = 12 mph. So he can run 14 * 12 = 168 miles.
Thus, the answer is 168.
