Answer:
   168 km
Step-by-step explanation:
Let x represent the distance Tyler drives at the slower speed, and let y represent the distance at the higher speed. Using time = distance/speed, we can write equations for the total travel time:
   x/42 +y/105 = 2.5
   x/28 +y/60 = 4.0 . . . . . 1.5 hours more than the usual 2.5 hours
Multiplying the first equation by 210, we have ...
   5x +2y = 525
Multiplying the second equation by 420, we get ...
   15x +7y = 1680
Subtracting 3 times the first of these equations from the second, we have ...
   (15x +7y) -3(5x +2y) = (1680) -3(525)
   y = 105
Putting this into the very first equation, we get ...
   x/42 + 105/105 = 2.5
   x/42 = 1.5 . . . . . . subtract 1
   x = 63 . . . . . . . . .multiply by 42.
The total distance to Tyler's parents' house is ...
   63 km + 105 km = 168 km

If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.
Out of these, Bloopin and Rudy are together in 4!=24 times.  Similarly Rudy and Bloopin will be together 4!=24 times.  So the number of ways they are not together is 120-24-24=72 ways.
