The Llesis family drove and hiked 6 hours to their vacation spot. They drove an average of 50 miles per hour and hiked an average of 5 miles per hour less than half their speed when they drive. If it took them 1.5 hours to hike, how far was their vacation spot?
Half the average speed of Llesis family driving is 50/2 = 
<gadget id="calculator">50/2</gadget>
<output>25</output>
25 miles per hour.
Hence, their average speed hiking was 25 - 5 = 
<gadget id="calculator">25-5</gadget>
<output>20</output>
20 miles per hour.
So, they hiked 20 x 1.5 = 
<gadget id="calculator">20*1.5</gadget>
<output>30</output>
30 miles.
It took them a total of 6 - 1.5 = 
<gadget id="calculator">6-1.5</gadget>
<output>4.5</output>
4.5 hours driving.
So, they drove 50 x 4.5 = 
<gadget id="calculator">50*4.5</gadget>
<output>225</output>
225 miles.
Therefore, their vacation spot was 30 + 225 = 
<gadget id="calculator">30+225</gadget>
<output>255</output>
255 miles far.
