You can probably figure out this answer in your head, with a bit of thought: Notice that a distance of 32 city blocks is 4 times as long as 8 city blocks. This means it would take you 4 times as long. And 4 times 25 minutes is 100 minutes or 1 hour and 40 minutes. On the other hand, if you'd like some practice using the distance/time formula, compute your walking speed using the general formula for distance and speed: distance = speed × time Or speed = walking speed = walking speed = Calculate the time it will take you to walk 32 city blocks. Use the same formula for distance and speed: distance = speed × time or time = time minutes Converting 100 minutes to hours and minutes: 100 minutes = 60 minutes + 40 minutes = 1 hour + 40 minutes Tip: This problem may also be solved using ratio and proportion.
