Question: You walk twice as fast as Mr. Harris, and Mr. Harris took 2 hours to walk to the store. If your destination is 3 times further away than the store Mr. Harris walked to, how many hours will it take you to get there? Think carefully first, then make a decision:
First we find out how long it would take Mr. Harris to walk to your destination, which we find by multiplying his 2 hour walk by 3 since your destination is 3 times further away, meaning it would take him 2 * 3 = 6 hours. Since you walk twice as fast, it would take you half the time. Half of 6, 6 / 2 = 3 hours in total. So the answer is 3.
