A wild tiger escapes the zoo.  He escapes at 1 AM and zookeepers do not notice he is missing until 4 AM.  He runs at a speed of 25 mph.  It takes 2 more hours to find him but after 4 hours of running, the tiger slows his speed to 10 mph.  He then gets chased for half an hour going 50 mph.  How far away from the zoo was he caught?
He was running for 4-1=
<gadget id="calculator">4-1</gadget>
<output>3</output>
3 hours.
So in that time he runs 3*25=
<gadget id="calculator">3*25</gadget>
<output>75</output>
75 miles.
Since he slowed down after 4 hours, the time he spent running at 25mph was an additional 4-3=
<gadget id="calculator">4-3</gadget>
<output>1</output>
1 hours.
So in the first hour they were finding him, he ran 1*25=
<gadget id="calculator">1*25</gadget>
<output>25</output>
25 miles.
In the second hour they were finding him, he ran 1*10=
<gadget id="calculator">1*10</gadget>
<output>10</output>
10 miles.
Finally, during the chase, he ran 50*.5=
<gadget id="calculator">50*.5</gadget>
<output>25</output>
25 miles.
So he is 75+25+10+25=
<gadget id="calculator">75+25+10+25</gadget>
<output>135</output>
135 miles away.
