A hiker walking at a constant rate of 4 miles per hour is passed by a cyclist travelling in the same direction along the same path at a constant rate of 36 miles per hour. the cyclist stopswaits for the hiker 5 min after passing her while the hiker continues to walk at her constant rate. how many minutes must the cyclist wait until the hiker catches up	Choose the correct choice from the following choices:
A) 6 2/3
B) 15
C) 20
D) 25
E) 40
Here is how I did it:   The cyclist travels 36 miles in 60 mins, so in 5 mins he will travel [(36*5)/60] miles, which equals 3 miles in 5 mins.   Now the hiker travels 4 miles in 60 mins. To travel 3 miles, he will take [(60*3)/4=

<output>45</output>
45 mins.   Hence 45-5= 
<gadget id="calculator">45-5</gadget>
<output>40</output>
40 mins   40
<result>E</result>
