On a 20 mile course, Bil bicycled at an average rate of 30 miles per hour for the first 12 minutes and without a break, ran the rest of the distance at an average rate of 8 miles per hour. How many minutes did Pat take to cover the entire course? Pick one:	A) 75	B) 105	C) 117	D) 150	E) 162
At an average rate of 30 miles per hour in 12 minute (1/5 hours) Bil covers (distance) = (time) * (rate) = 1/5*30= 
<gadget id="calculator">1/5*30</gadget>
<output>6</output>
6 miles, thus she should cover the remaining distance of  20 - 6= 
<gadget id="calculator"> 20 - 6</gadget>
<output>14</output>
14 miles at an average rate of 8 miles per hour.   To cover 14 miles at an average rate of 8 miles per hour Pat needs (time)= (distance)/(rate) = 14/8= 
<gadget id="calculator">14/8</gadget>
<output>7/4 = around 1.75</output>
1.75 hours= 105 minutes.   Therefore Bil needs total of   12 + 105= 
<gadget id="calculator">  12 + 105</gadget>
<output>117</output>
117 minutes to cover the entire course.   Answer: 117.
