Gary likes to walk around the edge of the local park, which is a rectangle that measures 1.5 miles by 6 miles. If he walks at 3 miles/hour, how many hours does he spend walking?
First find the length of the two long sides of the park: 6 miles * 2 = 
<gadget id="calculator">6*2</gadget>
<output>12</output>
12 miles.
Then find the length of the two short sides of the park: 1.5 miles * 2 = 
<gadget id="calculator">1.5*2</gadget>
<output>3</output>
3 miles.
Then add those two lengthes to find the total distance around the park: 12 miles + 3 miles = 
<gadget id="calculator">12+3</gadget>
<output>15</output>
15 miles.
Then divide the total length by Gary's speed to find how long he spends walking: 15 miles / 3 miles/hour = 
<gadget id="calculator">15/3</gadget>
<output>5</output>
5 hours.
