He was running for 4-1=<<4-1=3>>3 hours

So in that time he runs 3*25=<<3*25=75>>75 miles

Since he slowed down after 4 hours, the time he spent running at 25mph was an additional 4-3=<<4-3=1>>1 hours

So in the first hour they were finding him, he ran 1*25=<<1*25=25>>25 miles

In the second hour they were finding him, he ran 1*10=<<1*10=10>>10 miles

Finally, during the chase, he ran 50*.5=<<50*.5=25>>25 miles

So he is 75+25+10+25=<<75+25+10+25=135>>135 miles away

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?
