The ratio between the speeds of two Bullet trains is 7: 8. If the second Bullet train runs 460 kms in 4 hours, then the speed of the first train is: Choose the correct choice from the following.
A) 100.6 km/hr.	B) 37.25 km/hr.	C) 90.25 km/hr.	D) 94.25 km/hr.	E) 96.25 km/hr.
Let the speed of two bullet trains be 7x and 8x km/hr.   Then, 8x = (460/4)=

115   x= (115/8)= 
<gadget id="calculator">(115/8)</gadget>
<output>115/8 = around 14.375</output>
14.375   Hence, speed of first bullet train= (7 x 14.375) km/hr = 100.6 km/hr.   100.6 km/hr.
