An ant walks an average of 500 meters in 60 minutes. A beetle walks 15% less distance at the same time on the average. Assuming the beetle walks at her regular rate, what is its speed in km/h?  Select the correct option.
A) 1.0	B) 0.5	C) 0.75	D) 0.425	E) 0.3
the ant walks an average of 500 meters in 60 minutes   500 meters in 1 hours   the beetle walks 15% less distance = 500-75= 
<gadget id="calculator">500-75</gadget>
<output>425</output>
425 meters in 60 minutes   0.425 km in 1 hours   speed= 0.425*1= 
<gadget id="calculator">0.425*1</gadget>
<output>0.425</output>
0.425 km/h   I guess option 0.425 should be 0.425
