Lizzy: 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?.
Me: Hmmm, let me think. I think this is the detailed solution:
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. Final answer: 168.
