The train consists of 6 carriages, 20 meters long each. The gap between the carriages is 1 meter. If the train is moving at a constant speed of 60 km/h, how much time will it take the train to run through a 1 kilometer tunnel?
Choose the most appropriate option
A) 1^1/8 minutes	B) 1^1/2minutes	C) 1^3/4 minutes	D) 2 minutes	E) 2^1/4 minute
The length of the train is 6∗20 plus five 1 meter gaps, so it's 6∗20+5=125 meters;   The length that should be traveled by train is  1+0.125= 
<gadget id="calculator"> 1+0.125</gadget>
<output>1.125</output>
1.125 kilometers;   Time=Distance/ Rate=1.125/60 hours or 1.125/60∗60=1.125=1^1/8minutes.   1^1/8 minutesnswer: 1^1/8 minutes
