The biggest waterslide at Five Flags is 300 feet long, and people slide down at 60 feet/minute. The second biggest waterslide is 240 feet long, but steeper, so people slide down at 80 feet/minute. How much longer does it take to ride the biggest slide compared to the second biggest slide?
First find the ride length of the biggest slide: 300 feet / 60 feet/minute = 
<gadget id="calculator">300/60</gadget>
<output>5</output>
5 minutes.
Then find the ride length of the second biggest slide: 240 feet / 80 feet/minute = 
<gadget id="calculator">240/80</gadget>
<output>3</output>
3 minutes.
Then subtract the ride length of the second longest slide from the longest slide to find the difference: 5 minutes - 3 minutes = 
<gadget id="calculator">5-3</gadget>
<output>2</output>
2 minutes.
