John walks twice as fast as Tony and arrives 3 hours before Tony. Find the speed of each. : Let s = Tony's walking speed then 2s = John's walking speed : Write a time equation: Time = dist/speed : John's time + 3 hrs = Tony's time + 3 = multiply by 2s, results: 10 + 2s(3) = 2(10) 10 + 6s = 20 6s = 20 - 10 6s = 10 s = s = 1 mph is Tony's speed then 2(1) = 3 is John's speed : : Check solution with a calc by finding the times 10/1.67 ~ 6 hrs 10/3.33 ~ 3 hrs; a 3 hr difference
